摘要

本文采用金属有机骨架(mof)技术，以一种经济有效的方法去除废水中的刚果红。采用溶剂热处理法制备了含Co-MOF，并用SEM、TG和XRD对其结构进行了表征。研究了mof对废水中CR的去除效果，并对其吸附动力学进行了研究。结果表明，拟二级动力学模型能较好地描述CR的去除，Co-MOF在5 h内的最大吸附量为355.2 mg/g。考察了不同pH条件下mof的吸附能力。这项工作凸显了mof在污水处理中的广阔应用前景。

Synthesis of Metal–Organic Frameworks for the Adsorption of Congo Red from Wastewater

In this paper, metal–organic frameworks (MOFs) are applied to get rid of Congo red from effluent in an inexpensive and effective manner. Co-containing MOFs (Co-MOF) were prepared via solvothermal treatment, and their structures were tested by performing SEM, TG, and XRD. The MOFs were studied for the removal of CR from wastewater, and the kinetics of the adsorption process were investigated. The results indicated that the pseudo second-order kinetic model properly describes the removal of CR and the maximum adsorption capacity within 5 h is 355.2 mg/g for Co-MOF. The adsorption capacity of the MOFs was evaluated under different pH conditions. This work highlights the broad application prospect of MOFs in sewage disposal.
