摘要: 本文以Zn(NO3)2∙6H2O为锌源，2-甲基咪唑为有机配体，分别在甲醇、纯水和氨水三种溶剂中合成了三种不同类型的类沸石咪唑酯骨架结构材料ZIF-8，包括ZIF-8 (甲醇)、ZIF-8 (纯水)和ZIF-8 (氨水)。通过研究ZIF-8吸附SDS的热力学、动力学和吸附前后表面化学探讨了ZIF-8吸附SDS的机理，机理为ZIF-8 (氨水)通过NH+与SDS磺酸根之间的螯合作用与静电作用吸附SDS分子。
Abstract: Using Zn(NO3)2∙6H2O as zinc source and 2-methylimidazole as organic ligand, three different types of zeolite-like imidazolate framework materials ZIF-8 were synthesized in methanol, pure water and ammonia water, respectively, including ZIF-8 (methanol), ZIF-8 (pure water) and ZIF-8 (ammonia). The mechanism of ZIF-8 adsorbing SDS was discussed by studying the thermodynamics, kinetics and surface chemistry before and after ZIF-8 adsorbing SDS. The mechanism is that ZIF-8 (ammonia) adsorbs SDS molecules through the chelation and electrostatic interaction between NH+ and SDS sulfonate.
