沉淀双点滴定法测定盐酸左旋咪唑

以Ag^＋作滴定剂,分别用双点滴定法和传统电位滴定法对盐酸左旋咪唑片进行了测定。试液的配制采用了过滤和不过滤两种方法。测定结果表明：所有方法测得的结果均在《药典》允许的范围之内;本法测定结果与《药典》规定方法的对照偏差约为2%-3%;采用过滤和不过滤两种方法配制试液的测定结果之间的偏差约为1%。

Determination of levamisole hydrochloride by precipitation double-point titrimetry

According to the chinese pharmacopoeia the determination method for levamisole hydrochloride is non-aqueous titration.In this work,levamisole hydrochloride is determined by double-point titrimetry and traditional potentiometric titrimetry respectively using silver ion as the titrant in an aqueous solution.There are two kinds of test solution preparation,namely filtration and non-filtration. The determination results in this paper have the following features.Firstly,both analysis data got from double-point t...
