[Application of charge transfer reaction in the determination of aminosalicylate sodium].
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 40-160 microg/mL of aminosalicylate sodium. The apparent molar absorptivity of the complex at 660nm is 1.17 X 10(3)L x 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.
