介绍用毛细管电泳仪测定煤和干酪根中有机酸的分析方法。实验和研究表明 ,用 0 .4mmol/L溴化十六烷基三甲铵和 0 .8mmol/L邻苯二甲酸氢钾的混合溶液作电解质 ,在 2 5kV的电压下分析经水解处理成溶液的样品 ,操作简单 ,可以测定煤和干酪根中 11种有机酸 ,精密度、回收率令人满意。对有机酸与孔隙度的关系、煤中不同组分产有机酸的能力及其与孔隙发育的关系等给出了初步地质应用实例。图 2表 2参 3 (王汇彤摘 ) Introduction to the method for the determination of organic acids in coal and kerogen by capillary electrophoresis. Experiments and studies have shown that with 0. 4mmol / L cetyltrimethylammonium bromide and 0. 8mmol / L potassium hydrogen phthalate solution as an electrolyte, at a voltage of 2kV analysis was hydrolyzed to a solution of Samples, easy to operate, can determine 11 kinds of organic acids in coal and kerogen, precision, the recovery rate is satisfactory. The preliminary geological application examples are given concerning the relationship between organic acids and porosity, the ability of different components of coal to produce organic acids and their relationship with pore development.
