摘　　要：本文根据草酸根使磺水杨酸铁络合物的颜色变浅的原理进行草酸根的测定，特点是可利用一般药品和仪器进行分光光度测定操作，快速、准确、灵敏度高，测定下限可达１．０７×１０￣（－４）ｇ。经２年来的生产实践使用证明，是一种测量低含量草酸根的好方法。On the basis of the fact that the presence of oxalate leads to the lightening ofthe colour of Fe Ⅲ-sulpho-salicylic complex ,oxalate was determined by a spectrophotometricmethod using conventional reagents and instruments. The lower limit of detection was 1. 07×10￣(-4)g. The production practice for two years shows that it is a suitable method for deter-mining low concentraction oxalate.
