Abstract :
Water is vital to humans, animals and the entire ecosystem. However, its quality is deteriorating every dawn due to increased industrial advancements in our contemporary society leading to careless discharge of both organic and inorganic pollutants to the environment. This is not limited to metal ions which are eventually disposed to water bodies. Efforts to their remediation has yielded insignificant results as the used decontamination conventional techniques are costly. The use of adsorption using locally available adsorbents from agricultural wastes have increased research interest. Jackfruit rags (JR), a waste of Jackfruit was utilized as an adsorbent in lead (II) ions de-contamination from water. Powdered adsorbent was characterized using FT-IR which showed the presence of hydroxyl (-OH) and carboxylate (-COOH), carbonyl (-C=O) and ether (-C-O-C-) as important adsorption sites for lead (II) ions adsorption. The influence of contact time, pH, adsorbent dose, temperature and initial lead (II) ions concentration was investigated by batch adsorption technique. The optimal pH, time, dosage, temperature and initial lead (II) concentration was found to be: 5, 30 minutes, 0.08 g, 25 oC, 30 mg L-1 respectively. Isotherm studies showed that Freundlich model best described the lead (II) ions adsorption with adsorption capacity of 4.6716 mg/g which described a physisorption process. Kinetic parameters suggested the pseudo-second-order adsorption models best described the adsorption process. Thermodynamic functions of , and showed that lead (II) ions adsorption onto JR adsorbent was spontaneous, exothermic, non-entropy driven and physisorption in nature. The findings of the study showed that Jackfruit rags can be applied as an alternative, cheap and eco-friendly adsorbent in heavy metal ions removal from drinking water both at household level and industrial level.
