氢溴酸后马托品滴眼剂含量测定方法一般制剂手册均采用中和法,但该法终点不明显,误差颇大,不是一个理想的测定方法。据文献记载:氯溴酸后马托品在0.1N硫酸液中,在波长252nm、258nm、264nm处有三个吸收峰,为此我们试用紫外分光光度计进行测定,取得较满意的结果。 Determination of the content of horsetail hydrobromide eye drops General preparation manuals are used and neutralization method, but the end of the method is not obvious, the error is quite large, not an ideal method of determination. According to the literature, chlorhexidine chlorotrope in 0.1N sulfuric acid solution has three absorption peaks at 252nm, 258nm and 264nm wavelength. For this reason, we try UV spectrophotometer to get better results.
