摘要
本文用偏最小二乘-紫外分光光度法同时测定复方水杨酸搽剂中水杨酸、间苯二酚和苯酚的含量。平均回收率分别为:100.4±0.6%、101.5±0.8%和99.5±1.0%(置信度95%)。实测3批样品,结果准确、可靠。
hree components of salicylic acid, resorcinol and hydroxybenzene in compound salicylic acid liniment were determined simultaneously using PLS method. The average recovery of three components were 100.4 ± 0.62% , 101.5 ± 0.78% and 99.5 ± 1.01% respectively (confidence 95%). Three batches of sample were determined, and the result were accurate and reliable.
