摘要:

采用一阶导数光谱测定盐酸丁卡因滴眼液含量,取其导数光谱特征振幅作为定量信息,并可涓除对羟基苯甲酸乙酯的干扰,操作简便。相关系数r==0.9997,回收率99.55%(RSD=0.38%)

Abstract:

Absttact:The content of tetracainc hydrochloride was determined by first order deriyative spectrophotometry. The absolute value of valley amplitude was used for the quantitative determination. The average recovery was 99.55% (RSD = 0.38%), r = 0.9997.

Key words: first order derivative spectrophotometry tetracaine hydrochloride
