采用双波长法对对氯水杨酸的纯度进行了测定。对氯水杨酸在乙醇中的最大吸收波长为243 nm，副产物等吸收总波长为267 nm。测定纯对氯水杨酸的标准纯度都超过99.5%，测定市售3种对氯水杨酸的纯度在97.8%~98.0%。研究表明，该方法操作简单，分析数据准确可靠。
採用雙波長法對對氯水楊痠的純度進行瞭測定。對氯水楊痠在乙醇中的最大吸收波長為243 nm，副產物等吸收總波長為267 nm。測定純對氯水楊痠的標準純度都超過99.5%，測定市售3種對氯水楊痠的純度在97.8%~98.0%。研究錶明，該方法操作簡單，分析數據準確可靠。

Use dual-wavelength method to determine the purity of p-chlorine salicylic acid. The maximum absorption wavelength of p-chlorine salicylic acid in ethanol is 243 nm. The total absorption wavelength of byproducts is 267 nm. Determination of the standard purity of pure p-chlorine salicylic acid more than 99 . 5%. Determination of the purity of three kinds of commercially available p-chlorine salicylic acid was 97. 8 % ~98. 0 %. Studies show that the method is simple,the analytical data is accurate and reliable.
