摘要
本文对4-(2-吡啶偶氮)间苯二酚(PAR)测定锌制剂含量的方法进行了研究。实验结果表明,本法简便、快速、结果准确、灵敏度高,重视性好、线性范围宽。回收率为100±0.18%,r=O.9999(n=5),本法测定结果同EDTA络合滴定法及锌试剂法比较,经F、t检验无显著差异。
A PAR method of assaying zincic preparations was reported in this paper.The method has such advantages as simplicity, rapidity, high sensitivity andexcellent linearity (r=0.9999, n=5). The recovery is 100.0±0.18%. Thecoefficient of variation (CV%) is 0.36.
