摘    要:采用十六烷基三甲基溴化铵(CTMAB)制备改性斜发沸石,重点研究了改性剂的用量、改性时间、改性温度对改性白银斜发沸石吸附对硝基苯胺的影响.同时对斜发沸石改性前后的吸附性能进行了比较.结果表明,CTMAB改性的最佳时间为4 h,最佳浓度为10 g/L,改性温度对沸石吸附有机物的影响不大.改性斜发沸石对对硝基苯胺的吸附明显高于天然斜发沸石,且吸附等温线符合Frendlich方程.

关 键 词:斜发沸石  改性  对硝基苯胺  吸附

Abstract:The modifying clinoptilolit was prepared by using hexadecyltrimethylammonuium bromide(CTMAB) surfactants.The effect of the amount of CTMAB ,modifying time and modifying temperature on modifying clinoptilolit adsorption of p-nitroaniline was specially discussed and the adsorptive ability of p-nitroaniline of nature clinoptilolit and that of modified clinoptilolit was compared.it was found that the optimum time for modifying clinoptilolit was 4 h and the optimum concentration was 10 g/L.The modify temperature had little effect on clinoptilolit adsorption.The ability of modified clinoptilolit for adsorbing pnitroaniline was obviously higher than that of nature clinoptilolit.The adsorption of p-nitroaniline on modified clinoptilolit agreed well with Frendlich isothermal adsorption equation.
Keywords:Clinoptilolit  Modified  P-nitroaniline  Adsorption
