采用氯化铁对累托石进行柱撑改性,研究了最佳改性条件和热力学规律.氯化铁与累托石进行阳离子交换,调节pH,完成羟基化,制备出羟基铁交联累托石.试验得到的最佳条件为:羟基铁交联pH=7,氯化铁用量0.5 mmol/g,液固比25∶1,温度60 ℃,阳离子交换时间6 h,羟基铁交联时间3 h.在此条件下制备的羟基铁交联累托石对亚甲基蓝的吸附量为163.67 mg/g,吸附量较未改性的累托石有了明显的增加.热力学分析表明:改性累托石吸附亚甲基蓝过程的热力学符合Langmuir模式.

Hydroxyferrum rectorite was prepared by using FeCl3 as the crosslinking agent, and the best modifying conditions and absorption principle of thermodynamics for methylene blue trihydrate were studied. Hydroxylferrum crosslinked rectorite was prepared through regulating pH after cation exchanged between FeCl3 and rectorite. The best modifying conditions of rectorite were as fellow:the crosslinked pH 7, FeCl3 0.5 mmol/g,the ratio of liquit to solid 25∶1,the crosslinked temperature 60 ℃,the cation exchange time 6 h,the pillared time 3 h.The hydroxyferrum crossedlinked retorite prepared with the best condition has better adsorption capability than original rectorite,the adsorption quantity for methylene blue trihydrate reaches 163.67 mg/g. Thermodynamic analysis shows that isothermal adsorption law of hydroxyferrum crosslinked rectorite for methylene blue trihydrate accords with Langmuir model.
