Use of hydrazide derivative of poly methylacrylate for the removal of cupric ions from solutions

The hydrazide derivative of poly methylacrylate (PMA) was synthesized and used for removal of cupric ions (Cu2+) as an adsorbent from industrial effluent. Dimethylsulfoxide was used to chemically activate the synthesized PMA. Batch adsorption experiments were performed to examine the effects of initial concentration of Cu2+ ion, adsorbent dosage, temperature, and stirring rate on the adsorption of Cu2+ from the wastewater. It was found via isotherm studies that the Langmuir isotherm formulation best described the process of adsorption. Kinetic studies showed that the adsorption process had a pseudo-first-order reaction model. Chemically activated PMA is a cost-effective and efficient alternative to remove metal ions from effluent streams.
