羧基修饰的吸附树脂对1,2-苯并异噻唑-3-酮(BIT)的吸附研究
Study on the Adsorption of 1,2-Benzisothiazolin-3-One (BIT)with the Adsorption Resins Modified with Carboxyl
摘要
Abstract
The resins modified with trimellitic anhydride (named ZT3) or pyromellitic dianhydride (named ZT4) during the post-crossing of chloromethyl low crosslinking macroporous poly-styrene resin were prepared and characterized by BET.The adsorption performance of BIT onto ZT3 and ZT4 was studied through static and kinetic adsorption experiment with the commercial Amberlite XAD-4 as a contrast.The results showed that ZT3 and ZT4 resins had better adsorption capability to BIT than that of Amberlite XAD-4.Langmuir and Freundlich isotherm equation can fit the adsorption isotherm of BIT onto ZT3 and ZT4 perfectly.Furthermore,the capacities of ZT3 and ZT4 resins decrease with the increasing pH of solution.关键词
