| Abstract: | The present investigation reports the possibility of using Acacia saligna and Delbergia sisso pods to remove Cd(II) from aquatic systems in the form of calcium alginate modified immobilized composite beads (CAM-ASPCB and CAM-DSPCB). Batch and fixed bed column studies were carried out under various process affecting parameters. Maximum metal removal efficiency of 92% by CAM-ASPCB and 85% by CAM-DSPCB was observed under optimized conditions. Pseudo-second-order kinetic model, intra-particle diffusion, and Freundlich isotherm were found fitted well. The regeneration of the sorbents were found effectively high showing up to 10 cycles for simulated solution and up to 3 cycles for industrial effluent. |
