啶虫脒在超高交联吸附树脂上的吸附及脱附性能研究

本文从动态和静态的角度研究了均苯四甲酸酐修饰的超高交联吸附树脂（PMAR）和1，2，4-苯三酸酐修饰的超高交联吸附树脂（TMAR）对啶虫脒的吸附和脱附行为。结果表明：两种树脂对啶虫眯的吸附和脱附效果都比较好，TMAR的静态吸附量为470．9mg·g^-1干树脂，饱和吸附量为562．7mg·g^-1干树脂；PMAR的静态吸附量为453．4mg·g^-1干树脂，饱和吸附量为559．1mg·g^-1干树脂。两种树脂都易于脱附，用2mol·L^-1 HCl：乙醇（体积比1：1）作脱附剂，温度323K，脱附剂体积为9．5BV（床体积）时，PMAR的脱附率为98．13％，TMAR的脱附率为99．83％。

Study of the Adsorption and Desorption Properties of Acetamiprid on Hypercrosslinked Polymeric Adsorbents

The adsorption and desorption behavior from dynamic and static angle of acetamiprid on the hypercrosslinked polymeric adsorbent modified by pyromellitic dianhydride （PMAR） and the hypercrosslinked polymeric adsorbent modified by trimellitic dianhydride （TMAR） were studied. The results showed that., the adsorption and desorption performance of acet- amiprid on both resins were better. The static adsorption capacity of TMAR was 470. 9mg · per gram dry resin, the saturated adsorption capacity was 562.7mg · per gram dry resin; the static adsorption capacity of PMAR was 453.4mg · per gram dry resin, the saturated adsorption capacity was 559.1mg · per gram dry resin. Both resins could be easily desorbed. The desorption percent acetamiprid on PMAR was 98. 13% and the desorption percent acetamiprid on TMAR was 99.83% when using 9.5BV 2mol·L^-1 hydrochloric acid., ethanol （1 ： 1） as the desorbent at the temperature of 323K.
