新洁尔灭器械消毒液用于器械浸泡时,常加入0.5%亚硝酸钠,以防止器械生锈。因器械消毒液中含有新洁尔灭,故药典法不适合亚硝酸钠的含量测定。本文试用紫外分光光度法测定器械消毒液中亚硝酸钠的含量,获得了比较满意的结果,现介绍如下.
Bromogeramine device disinfectant for equipment soaked, often adding 0.5% sodium nitrite to prevent rusting equipment. Because of disinfection solution containing benzalkonium bromide, so pharmacopoeia method is not suitable for the determination of sodium nitrite. In this paper, UV spectrophotometry method for determination of equipment disinfectant sodium nitrite content, obtained more satisfactory results, are presented below.
