Abstract
AbstractThe column performance of silica‐coated, amino‐functionalized, superparamagnetic nanoparticles co‐integrated with Cynodon dactylon and Murraya koenigii plant extracts for the removal of CuII ions was evaluated. The co‐integrated nanoparticles were used as sorbent materials in fixed‐bed column studies, and the effects of inlet concentration, adsorbent bed depth, and flow rate were analyzed. Breakthrough time was calculated for various CuII inlet concentrations, depths of the adsorbent bed, and volumetric flow rates. Models such as Thomas, Yoon‐Nelson, and the bed depth model were evaluated to determine the experimental fit. The maximum breakthrough time for CuII ions of 1200 min was attained for a CuII inlet concentration of 100 mg L–1, sorbent bed depth of 3 cm, and volumetric flow rate of 1 mL min–1.
