铈-3,4-二羟基苯甲酸配合物的极谱研究
A STUDY ON OLAROGRAPHIC ADSORPTIVE WAVES OF COMPLEX OF Ce(IV)-3,4-DIHYDROXYBENZOIC ACID
【摘要】 本文研究了铈(Ⅳ)-3,4-二羟基苯甲酸配合物的极谱性质,测定出该配合物的组成为1:4;pH为9.75时的表观稳定常数β4为3.8×1013,经副反应系数校正得该配合物的稳定常数β4=1.7×1032。
【Abstract】 The polarographic adsorptive behaviors of complex of Ce ( IV )-3,4-dihydroxybenxoic acid are studied in this paper.The stability and composition of Cerium(IV) -3,4-dihydroxybenzoic acid complex are determined by the polarographic method. In ammonia - ammonia chloride buffer solution containing 0.5 mol.dm-3 sulfurous sodium at pH9.75, the composition of the complex is 1:4 with one Cerium(IV) and four 3,4-dihydroxybenzoic acid and the stability constant of the complex is 1.7×1032 .
