![]() ![]() The adsorption mechanism was investigated using energy dispersive X-ray (EDX), elemental mapping, and Fourier transform infrared (FTIR) techniques. Isotherms results showed excellent monolayer adsorption capacities of 330.90, 161, and 118.90 mg g –1 for Pb(II), Cu(II), and Ni(II), respectively, with a heterogeneous adsorption capacity of 25.40 mg g –1 for CIP. However, adsorption of heavy metal ions to the adsorbent was faster than that of CIP. ![]() Kinetics results fit well with the pseudo-second order (PSO) kinetics model for both inorganic and organic pollutants. ![]() Different batch adsorption experiments such as pH, reaction time and initial pollutant concentration effects were carried out to identify the adsorption condition to attain the maximum removal efficiency. The current study pertains to the synthesis of an EDTA-functionalized β-cyclodextrin-chitosan (β-CD-CS-EDTA) composite via a two-step process for the adsorptive removal of toxic heavy metallic ions (i.e., Pb(II), Cu(II), and Ni(II)) and antibiotic micropollutant, i.e., ciprofloxacin (CIP), from water.
