Removal of heavy metal ions Cd from aqeous solutions by using nanogel prepared from 2-acrylamido-2-methylpropane sulfonic acid and modified rice husk

The adsorption behavior of rice husk for cadmium ions from aqueous solutions has been investigated as a function of appropriate equilibrium , adsorbate concentrations and pH in a batch system. The experimental data were analysed by the Langmuir, Freundlich models of adsorption. The modified rice husk (MRH) were characterized by FTIR and TGA. The rice husk investigated in this study showed good potential for the removal of cadmium from aqueous solutions. The goal for this work is to develop inexpensive, highly available, effective metal ion adsorbents from natural waste as alternative to existing commercial adsorbents
