Abstract

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.

在高级废水处理中去除药物的新型沸石模板碳 (ZTC)

这篇科学文章研究了一种新型沸石模板碳（ZTC）对酮洛芬的吸附，X 射线衍射（XRD）显示该材料为 2 型沸石，其高比表面积证实了其 ZTC 性质。该材料具有出色的热稳定性，扫描电子显微镜（SEM）显示其结构清晰且均匀。动力学研究表明，伪一阶（PFO）模型最能说明吸附作用，吸附速度快，去除效率高。等温线结果显示，298 K 时的理论最大吸附容量为 280 mg g-1，这种吸附是自发、有利和放热的。ZTC 可以有效地使用长达 5 个吸附周期，这证明了它的稳定性。此外，在处理河水水源实际污水的实际应用中，污染物的去除率超过 84%。研究结果表明，ZTC 在环境修复过程和先进废水处理中具有广阔的应用前景。

期刊介绍： Microporous and Mesoporous Materials covers novel and significant aspects of porous solids classified as either microporous (pore size up to 2 nm) or mesoporous (pore size 2 to 50 nm). The porosity should have a specific impact on the material properties or application. Typical examples are zeolites and zeolite-like materials, pillared materials, clathrasils and clathrates, carbon molecular sieves, ordered mesoporous materials, organic/inorganic porous hybrid materials, or porous metal oxides. Both natural and synthetic porous materials are within the scope of the journal. Topics which are particularly of interest include: All aspects of natural microporous and mesoporous solids The synthesis of crystalline or amorphous porous materials The physico-chemical characterization of microporous and mesoporous solids, especially spectroscopic and microscopic The modification of microporous and mesoporous solids, for example by ion exchange or solid-state reactions All topics related to diffusion of mobile species in the pores of microporous and mesoporous materials Adsorption (and other separation techniques) using microporous or mesoporous adsorbents Catalysis by microporous and mesoporous materials Host/guest interactions Theoretical chemistry and modelling of host/guest interactions All topics related to the application of microporous and mesoporous materials in industrial catalysis, separation technology, environmental protection, electrochemistry, membranes, sensors, optical devices, etc.
