一、概述离子交换树脂是一类带有活性功能基,能通过所带的可交换离子与溶剂(水、有机溶剂、气体)中的其它离子进行交换或吸附的小颗粒状物质。它以有机高分子为主,包括吸附树脂、离子交换膜、离子交换纤维,螯合树脂、氧化还原树脂等;对于由无机金属离子组成的一般叫做无机离子交换剂。近 I. Overview Ion exchange resins are a group of small particulate materials with active functional groups that exchange or adsorb with other ions in the solvent (water, organic solvent, gas) by the exchangeable ions they carry. It is dominated by organic polymers, including adsorption resins, ion exchange membranes, ion exchange fibers, chelating resins, redox resins, etc .; for the inorganic metal ions commonly known as inorganic ion exchangers. near
