中国药典法规定盐酸麻黄碱片剂注射液的含量测定用容量法,此法手续繁杂且对环境有污染。曾纪炎等对该药的选择电极虽有过报道,但此种电极为内充液式膜电极,存在着使用不便、不易保存、寿命较短及性能不够稳定等缺点。我们在文献中曾研制了一种以尿醛树脂为框架的固态Ag/AgCl参比电极,后又在文献中报道了以此固态参比电极为基体的全固态阿托品电极和扑尔敏电极。本文在此基础上进一步研制了一种新型的全固态 Chinese Pharmacopoeia Act provides determination of content of ephedrine hydrochloride tablets injection volume method, this method complicated and polluting the environment. Although there are reports on the selection electrode of Zang Jianyan and other drugs, such electrodes have the disadvantages of inconvenience in use, difficulty in preservation, short life span and insufficient stability in performance. In the literature, we have developed a solid-state Ag / AgCl reference electrode based on a urea-formaldehyde resin, and later reported in the literature solid-state atropine and chlorpheniramine electrodes based on this solid-state reference electrode. Based on this, this paper further developed a new all-solid state
