γ-缩水甘油醚氧丙基三甲氧基硅烷为偶联剂,将三乙胺盐酸盐键合到硅胶上,制得了一种新型的强阴离子交换填料。通过FTIR红外光谱表征制备的季铵基硅烷与强阴离子交换(SAX)填料的基团,元素分析及失重法定量的测定SAX填料的交换容量为0.600meq/g,以苯甲酸为模型化合物对填料的吸附条件及性能进行考察,通过Langmuir等温吸附曲线拟合,计算得最大吸附量为0.140meq/g。
γ-glycidoxypropyltrimethoxysilane as a coupling agent, the triethylamine hydrochloride bonded to silica gel, a new type of strong anion exchange packing. The quaternary ammonium silane and strong anion exchange (SAX) packing groups were characterized by FTIR spectroscopy. The content of SAX packing was 0.600 meq / g as determined by elemental analysis and weight loss method. The adsorption of packing material by benzoic acid Conditions and properties were investigated. The maximum adsorption capacity was 0.140 meq / g by Langmuir isotherm curve fitting.
