A novel zeolite template carbon (ZTC) for pharmaceutical removal in advanced wastewater treatment

This scientific article investigates the adsorption of Ketoprofen using a novel zeolite template carbon (ZTC) characterized by X-ray diffraction (XRD) as a type 2 zeolite with a high surface area confirming its ZTC nature. The material exhibits excellent thermal stability, and scanning electron microscopy (SEM) reveals a well-defined and homogeneous structure. Kinetic studies indicate that the pseudo-first-order (PFO) model best describes adsorption, demonstrating rapid adsorption with high removal efficiency. Isotherm results reveal a theoretical maximum adsorption capacity of 280 mg g−1 at 298 K, which is spontaneous, favorable, and exothermic. The ZTC can be efficiently utilized for up to 5 adsorption cycles, demonstrating its stability. Moreover, practical application in treating real effluents from a river water source showed a removal efficiency exceeding 84 % for the contaminants. The findings suggest the promising potential of ZTC in environmental remediation processes and advanced wastewater treatment.
