中文摘要：

选用在有机废水处理中已经得到广泛使用的商业化树脂Amberlite XAD-4作参照，通过等温吸附实验和吸附动力学实验研究了单宁酸和邻羧基苯甲酰基修饰的吸附树脂（分别命名为FZH-11和FZH5）对1，2-苯并异噻唑-3-酮的吸附性能。结果表明，修饰后的树脂FZH-11和FZH5对1，2-苯并异噻唑-3-酮具有较高的吸附容量，吸附过程存在化学吸附作用。1,2-苯并异噻唑-3-酮在FZH-11和FZH5树脂上的吸附过程符合准一级动力学方程，颗粒内扩散是吸附过程的主要速度控制步骤。FZH-11和F-ZH5树脂经酸液脱附可重复利用，废水在得到有效治理的同时实现了1，2-苯并异噻唑-3-酮的资源化回收利用．

英文摘要：

Two types of adsorption resins were prepared by post-crosslinking of chloromethylated low-crosslinking macroporous polystyrene resins with tannic acid （named as FZH-11） and 2-carbonxylbenzoyl （named as FZH5）, respectively. The adsorption of 1,2-benzisothiazolin-3-one （BIT） onto FZH-11 and FZH5 was studied through static and dynamic adsorption experiments with the commercial resin Amberlite XAD-4 as reference. The results showed that both FZH-11 and FZH5 resins had good adsorption performance of BIT because of an obvious irreversible chemisorption process originated from carboxylic acid groups during chemical modification. The data of adsorption kinetics experiments of BIT on FZH-11 and FZH5 could be fitted well by the pseudo-first-order kinetic equation so that the intraparficle diffusion played a dominant role in the adsorption process. FZH-11 and FZH5 resins could be regenerated through acid-desorption, which contributed to the treatment of organic wastewater and the recovery of BIT.
