小咳合剂中氯化铵含量测定方法探讨

STUDIES ON CONTENT DETERMINATION METHOD OF AMMONIUM CHLORIDE IN ANTICOUGH MIXTURE FOU INFANT

本文应用甲醛法测定小咳合剂中氯化铵的含量,平均回收率为99.84%,CV=0.52%,与Mohr法相比,结果准确,精密度较高,克服了Mohr法的不足.

Determination of amm- onium chloride in anticough mixture for infant by formaldehyde method was repo in this paper. The average recovery ratio was 99.84%,coefficient of variation0.52%. Formaldehyde method has accu-rater results and higher accuracy thanMohr method. lhes can surmount difici-ent respest of Mohr method.
