This report focuses on the adsorptive potential of lab synthesized composite beads, made up of Xanthan Gum, Calcium Alginate and Na-A Zeolite. The adsorption was investigated in a batch mode by changing relevant parameters including the adsorbent dosage, metal ions present, initial pH, system temperature, and solution salt concentration. The XG-CA-Na-A composite beads showed promising signs removing ~99.5% cobalt ions and 98.3% nickel ions present in a synthesized nuclear power plant wastewater solution at an optimal pH and dosage of 5 and 2 g/L respectively. The adsorption process was also found to be spontaneous and endothermic with its mechanism best explained by the Pseudo-second-order kinetic model and the Langmuir isotherm model.
