Abstract

The preparation of a compound liquid ion exchanger used for the miniaturization of bile acid sensitive microelectrode is described. The liquid ion exchanger is 2% benzyldimethylhexadecylammonium cholate in decanol/0.1 M hexadecyltributylammonium taurocholate in 5% hexachlorobenzene, 0.5% bromoacetanilide O-dichlorobenzene. The slopes, detection limits, selectivity coefficients, drifts and response time of the various bile acid sensitive microelectrodes are evaluated and compared.

摘要

描述了一种用于胆汁酸敏感微电极小型化的复合液体离子交换剂的制备。该液体离子交换剂为在癸醇中的2%苄基二甲基十六烷基氯化铵胆酸盐/在5%六氯苯中的0.1M十六烷基三丁基氯化铵牛磺胆酸盐、在邻二氯苯中的0.5%溴乙酰苯胺。对各种胆汁酸敏感微电极的斜率、检测限、选择性系数、漂移和响应时间进行了评估和比较。
