Abstract

This work focuses on employing burned clay (FC) materials as a low-cost adsorbent to remove cadmium and lead ions from synthetic stormwater and to evaluate its performance and applicability as a supplementary component to remove Cadmium and Lead ions in an aqueous solution. The studies were carried out to look into the Cadmium and Leads' room-temperature adsorption isotherm and the effects of various variables. The primary adsorbate concentration, contact time, agitation speed, pH, and mass of the adsorbent have all been studied. According to the results, the optimal experimental conditions-pH=6, 0.45mg/l of Cadmium and 0.08 mg/L of Lead as adsorbate, 12 g of adsorbent, 250 rpm of agitation, and 2.0 hours of contact time -reduced Cadmium and Lead by 93 percent for fired clay. The experimental data were examined using the Langmuir and Frendlich isotherm models. The preferred model for Cadmium and Lead adsorption onto fired clay material, according to the results, was the Langmuir adsorption isotherm. This study clearly shows that fired clay particles can be employed as a low-cost adsorbent to take Cadmium and Lead out of water.
