分光光度法测定酸碱指示剂pka值的研究

SPECTROPHOTOMETRIC DETEMINATION OF DISSCIATION CONSTANTS OF SOME ACID-BASE INDICATORS

提出了测定政碱指示剂离解常数的光度方法．实测了数种酸碱指示剂的离解常数，结果满意．

In this paper. A method for the defermination of dissocation constants of acid-base indicatro has been proposed. The dissocation constants of some acid-base indicatiors have been determined spectrophotemetrically by the proposed method with satifactroy results.
