摘　　要：在洗必泰有特征吸收峰的２５８ｎｍ波长下，以紫外分光光度法测定洗必泰含量．与高氯酸滴定法相比，对洗必泰量≤２１０μｇ的稀释液，测定误差为０．９％～４．７％．The chlorhexidine content was measuredby ultraviolet spectrophotometry at the wavelengthof 258 nm where there is a characteristic absorptionpeak of chlorhexidine、As compared with perchloricacid titration measurement, the error in measuringthe diluted solution containing≤210 ug ofchlorhexidine was 0.9%～4.7%.
