Description
Summary:Nano scale zero valent iron has been a very effective tool to treat the heavy metals from wastewater. This study provides an effective method for the remediation of lead and cadmium from aqueous system using newly synthesized amino resin supported nano scale zero valent iron (RXI). Firstly, Amberlite XAD-4 was reduced to amino group followed by the synthesis of RXI. Multiple techniques like FT-IR, XRD, and SEM-EDS were used to investigate the synthesis of composite. Maximum removal of metal ions was achieved at pH 6, agitation time 120 min, initial concentration of metal ions 10 mg L –1 and 75 mg adsorbent dosage. Monolayer adsorption capacity was calculated to be 25 and 20 mg/g for lead and cadmium ions respectively. The pseudo second order kinetic model seemed to provide best fit to the uptake of lead and cadmium ions onto RXI surface.
