Abstract
for Cr@EA-PS). Such increased adsorption capacity is nearly 10-fold higher than the reported capacity of PS. Kinetic studies revealed that the adsorption process followed a pseudo-second-order model, indicating chemisorption as the primary adsorption mechanism. Isotherm analysis confirmed a favorable monolayer adsorption process exhibited by the three structures. The combination of chemical bonding and physical adsorption mechanisms was observed for Cr@EA-PS, explaining its performance superiority in removing Cd(ii) ions. Thus, the inorganic-organic composite exhibits the highest potential among the three introduced sorbents for practical applications in the field of wastewater treatment.
