Determination of salicylic acid and phenol in tinctura antipruritic by turnover curve spectrophotometry
-
摘要: 采用转换曲线分光光度法,根据吸收度的加和性同时测定了止痒酊中水杨酸和苯酚的含量,测定波长范围为255~270nm.本方法简便,结果可靠。Abstract: Based on the additivity of absorbances, a turnover curve spectrophotometry was used for the determimation of salicylic acid and phenol in tinctura antipruritic in the range of wavelengths from 255nm. The method was simple and reliable.
