1-氨基乙叉-1,1-二膦酸离解作用的研究

STUDY ON THE DISSOCIATION OF 1-AMINOETHYLIDENE-1, 1-DIPHOSPHONIC ACID

用pH电位法研究了AEDP的五级离解常数 ,计算了离解过程的热力学参数ΔG0 、ΔH0 、ΔS0 .

The dissociation of 1-aminoethylidene-1,1-diphosphonic acid in solution was studied by potentiometric tiration method.The dissociation constants were measured at various temperatures.The thermodynamic parameters,ΔG 0?ΔH 0?ΔS 0 for the dissociation process were calculated.At the same time,the complexcapability with Ca 2+ was studied.
