Ecological Study on Phosphorylated Amberlite IRA 400 Resin for the Removal of Cd (II) from Aqueous Solutions

According to aquatic ecology, the modified resin prepared from Amberlite IRA 400, acts as an adsorbent for the removal of cadmium(II) from aqueous solutions. In batch ecological studies, the optimization of pH, contact time and resin dose on removal of metal were studied. P=O functional groups that exist on the resin material were used to remove the metal in the aqueous solution environment. The isotherm patterns of Langmuir and Freundlich were analyzed from the experimental data. The feasible, spontaneous and exothermic nature of adsorption was confirmed in this ecological study. The adsorption kinetics study follows the pseudo-second-order model and film diffusion process.
