  Abstract
  The leaves of Anadendron parviflorum leaves (APL) were utilized as a low-cost bio-adsorbent in this experimental study to remove acid green 1 an aqueous solution that contains dye. Adjusting the method that was used in the adsorption of the dye molecules are contact time, adsorbent dose, initial concentration, temperature, addition of salt, particle size, pH, and zero point pH. Both pseudo first order and pseudo second order kinetics , which were used to study adsorption kinetics. The rate of adsorption of acid green 1 dye is associated with kinetics that are of the pseudo first order. As a result, the adsorption technique demonstrates that APL has a high efficient adsorption capacity for acid green 1 dye.

  Abstract
  Copper nanoparticle deposited on stilbite zeolite act as an effective catalyst for the synthesis of 2-(substituted phenyl)-3-(5i-methyl thiazole)-4-thiazolidinones (4), 2-(substituted phenyl)-3-(5i-methyl thiazole)-5-methyl-4- thiazolidinones (5) and 4-(substituted phenyl)-3-chloro-1-yl-(5i-methyl thiazole)-2-azetidinones (6). These compounds were synthesized by cyclic condensation of thioglycolic acid, thiolactic acid and chloroacetyl chloride in presence of triethyl amine with different Schiffbases. The structures of synthesized compounds have been characterized on the basis of IR and 1H NMR spectra.

  Abstract
  The study investigates the use of Matki seed husk (MtSH), a low-cost and abundant agricultural waste, as adsorbent for removing nickel metal ions from aqueous solutions. In this research, the effect of contact time, effect of temperature, effect of adsorption dose, pH and initial concentration of metal ions on MtSH adsorbent capacities has been investigated. The adsorption of Ni2+ metal ions was investigated by using pseudo-first and pseudo-second order kinetic models. The adsorption kinetics was well described by the pseudo-second-order kinetic model, and equilibrium data were successfully fitted to the Freundlich models. The optimum adsorption was observed at pH 5, with spontaneous and exothermic adsorption. The study recommends MtSH as a cost-effective and easily available bio-adsorbent for removing toxic heavy Ni2+ metal ions from industrial wastewater. The bio-adsorbent can be reused up to five times without significant loss of adsorption capacity. Overall, this present study demonstrates that Matki seed husk can be a promising low-cost bio-adsorbent for the removal of Ni2+ metal ions from aqueous solution, offering significant environmental benefits. The results of this study can be used to develop cost-effective and sustainable strategies for wastewater treatment and pollution control.

  Abstract
  The purpose of this research is to investigate the possible uses of synthesized and characterized metal oxide nanoparticles in a range of industries, including electronics, catalysis, and environmental remediation. The remarkable qualities of metal oxide nanoparticles, such as their large surface area, catalytic activity, and adjustable electrical and optical properties, make them very intriguing. Because of these qualities, they are perfect for many technical and industrial uses. This research used a chemical co-precipitation method to create oxide nanoparticles of zinc, copper, iron, and cobalt. Synthesized nanoparticles show potential for application in environmental cleanup, sensor development, and other high-tech fields due to their customized features.

  Abstract
  The oxidation of Isoprenaline, a pharmaceutical compound was studied kinetically in an aqueous medium using potassium dichromate as the oxidant using spectrophotometer at 520 nm. The reaction rate was found to be first order with respect to both the substrate and the oxidant while it is independent of acid concentration. Stoichiometric analysis revealed that one mole of potassium dichromate is required to oxidize three moles of Isoprenaline. Initially a complex intermediate i.e. chromate ester is formed in the rate determining step which later oxidized to form the product. The activation parameters like change in enthalpy ?H, change in entropy ?S and Gibbs free energy change ?G, were calculated based on the results. The positive value of enthalpy change indicates the reaction is endothermic while the negative value of change in entropy indicates highly ordered reaction. The reaction product was found Isoprenaline N-oxide which is easy to remove from the aqueous system. The research will be very helpful for the degradation of Isoprenaline in aqueous medium by dichromate in bulk and maintaining the environmental balance.

  Abstract
  This study investigates the impact of various environmental and nutritional factors on citric acid production by Aspergillus niger strains N2, N10, and N12. Soil samples collected from diverse locations were used to isolate fungal cultures, and citric acid production was evaluated under different conditions. The effects of pH on citric acid yield were analyzed, revealing that the optimal pH for citric acid production across all strains was 4.5. At this pH, strain N12 achieved the highest yield of 3.9 mg/mL, while strains N2 and N10 produced 3.8 mg/mL and 3.7 mg/mL, respectively. Acidic conditions, particularly between pH 3.0 and 4.5, were found to be favorable for citric acid production. Sucrose concentration was examined, with the highest citric acid yield observed at 13% sucrose. Strain N12 exhibited the maximum yield of 3.6 mg/mL at this concentration. Higher sucrose levels, ranging from 15% to 18%, resulted in decreased citric acid production, suggesting a potential inhibitory effect of excessive sucrose. The influence of magnesium sulfate (MgSO4) was assessed, identifying 20 mg/L as the optimal concentration for citric acid production. At this level, strain N12 produced 3.9 mg/mL of citric acid, while lower and higher concentrations led to reduced yields, highlighting the importance of balanced MgSO4 levels for efficient citric acid synthesis. Sodium nitrate (NaNO3) concentration was also varied, with the highest citric acid yield occurring at 400 mg/L. Strain N10 achieved the peak yield of 3.9 mg/mL at this concentration. Deviations from this optimal level resulted in decreased citric acid production, indicating that precise NaNO3 concentration control is crucial for maximizing yields. In conclusion, the study identifies optimal conditions for citric acid production in Aspergillus niger as a pH of 4.5, sucrose concentration of 13%, MgSO4 concentration of 20 mg/L, and NaNO3 concentration of 400 mg/L. These findings provide essential insights for optimizing fermentation processes to enhance citric acid production in industrial applications.

  Abstract
  This study investigates the potentiometric behavior of complexes formed between selected antibacterial medicinal drugs and transition metal ions. The study aims to elucidate the stability constants of these complexes and explore the implications for drug efficacy and metal ion chelation. Potentiometric titrations were performed to determine the stability constants of the drug-metal complexes in aqueous solutions at varying pH levels. The results provide insights into the coordination chemistry of these drugs, which could have significant implications for their pharmacological activity. Antibacterial drugs are widely used to treat bacterial infections, and their effectiveness can be influenced by their ability to form complexes with metal ions. Transition metal ions such as Fe²?, Co²?, Cu²?, and Zn²? play crucial roles in biological systems and can interact with drugs to form stable complexes. The study of these complexes is essential for understanding drug bioavailability.

  Abstract
  Heavy metal contamination in wastewater is a critical environmental issue, with metals like Chromium (Cr), Arsenic (As), and Lead (Pb) posing significant risks to both ecosystems and human health. Conventional treatment methods often fall short in efficiently removing these contaminants, particularly at low concentrations, and are associated with high costs and secondary pollution. This review paper explores the potential of bioadsorbents—natural materials derived from agricultural wastes, plant-based materials, animal by-products, and industrial residues—as an eco-friendly and cost-effective alternative for heavy metal removal. By examining the adsorption capacities, mechanisms, and effectiveness of various bioadsorbents, the study demonstrates their significant potential in wastewater treatment. The findings suggest that with further research and optimization, bioadsorbents could be widely adopted in industrial applications, providing a sustainable solution to heavy metal pollution.
