摘要
本文建立了表述变价态离子电极特殊行为的理论模型,阐明了S-δ经验式及用δ-pH作图法求双质子化离子pK_(a1)的潜在机理.提出更为简便而准确的pK_(a1)二阶微商计算法,并依据电极电位随溶液pH变化的关系求出pK_(a2).
A theoretical model has been proposed to describe the response behavior of the variable valency ion-selective electrode. The S-δ relationship for suoh electrodes has been deduced theoretically. A new and more exact method for determining pK_(a1)from the^2S/ pH^2-pH relationship has been suggested. pK_(a2)is determined from the E-pH relationship.
