报道了一种阿托品选择性电极的研制和应用。该电极是将对阿托品敏感的聚氯乙烯膜涂敷于pH玻璃电极球部表面而制成。在0.10mol/L磷酸盐缓冲溶液(pH4.0)中, 所制电极对阿托品的Nernst响应线性范围为1.70×10~-~5～2.00×10~-~2mol/L阿托品, 响应斜率为55.8mV。电极响应时间小于45s, 使用寿命大于6个月。而且具有制作简单、使用方便的特点。已将该电极应用于硫酸阿托品制剂中测定阿托品的含量, 结果满意。

n ion selective electrode of atropine has been prepared with atropine tetraphenylborate ion pair complex as the electroactive material.The electrode exhibited a linear Nernst response in the range of 1.70×10 -5 to 2.00×10 -2 mol/L for atropine with a slope of 55.8mV per decade in pH4.0 phosphate buffer solution.The response time is less than 45s and the lifetime of the electrode is longer than 6 months .The electrode has been used for determining of atropine contents in atropi...
