摘要
本文研究了对氨基水杨酸钠与２，６－二氯醌氯亚胺的荷移反应，确定了反应条件。反应在丙酮介质中进行，二者形成１１的络合物，其最大吸收波长为６６０ｎｍ，表观摩尔吸光系数为１．１７×１０３Ｌｍｏｌｃｍ－１，用拟定方法测定对氨基水杨酸钠制剂的含量，获得满意的结果。
A spectrophotometric method for the determination of aminosalicylate sodium has been developed based on the charge transfer reaction.The Beer′s law is obeyed in the range of 40—160μg/mL of aminosalicylate sodium.The apparent molar absorptivity of the complex at 660nm is 1.17×10~3L·mol^-1.The average standard deviation of ten determination is 0.67%.The composition of aminosalicylate sodium 2,6-Dichloroquinone chlorimide complex is 1∶1.The proposed method has been applied to the determination of aminosalicylate sodium tablets with satisfactory results.
