| 摘 要： | 本文在pH9的硼砂介质中,用硝酸银标准溶液沉淀磺胺甲基异噁唑后,以原子吸收法测定剩余的银量而测得磺胺类药物有效成分的含量。测定回收率达99.0％～100.5％,标准偏差为0.23～0.29,结果与药典规定的永停终点法一致。

| Abstract: | In this paper, sulfa drug was determined by determination of excess Ag by AAS after precipitating sulfamethorazole (SMZ) using silver nitrate standard solution in pH9 borax medium. The percentage recoveries were found to be 99. 0%~100. 5% and the standard deviation was 0. 23~0. 29. The results were satisfactory and in good agreement with those given by dead-stop end point method provided by the Pharmacopoeia of China. |
