摘要： 金属-有机凝胶的制备与吸附性能研究是结合当前科研前沿研究成果设计改进的一个综合性物理化学实验。以均苯三甲酸和硝酸铁为主要原料，通过简单混和制备FeBTC金属-有机凝胶，并通过不同干燥方法干燥FeBTC凝胶。研究了FeBTC的组成结构，并通过N2吸附脱附测定FeBTC的比表面积。进一步研究FeBTC对Cr2O72−的吸附动力学，用于废水处理。

关键词: 金属-有机凝胶, 吸附动力学, 干燥方法

Abstract: A comprehensive physical chemistry experiment has been designed about the preparation and adsorption performance of metal-organic gel based on cutting-edge scientific research. FeBTC metal-organic gel was prepared by simple mixing of 1,3,5-benzenetricarboxylic acid and ferric nitrate, and FeBTC was dried using different drying techniques. The structure of FeBTC was investigated. The specific surface area of FeBTC was determined through N2 adsorption and desorption isotherms. The adsorption kinetics of FeBTC towards Cr2O72− was studied for wastewater treatment.
