摘要
本文基于安乃近将Ｆｅ３＋还原为Ｆｅ２＋，用硫氰酸钾作Ｆｅ３＋的显色剂，籍硫氰酸铁退色光度法测定了药物中的安乃近，结果与紫外光度法、药典法基本一致。
Analginum in
preparations was determined by the ironic rhodanate fading spectrophotometric method,based on
Fe 3+ reduced into Fe 2+ by analginum and reacting on potassium rhodanate.The obtained
results were in agreement with those of the iodine titration method and the ultraviolet photometric
method.
