本文采用了钠离子选择电极,在含有30%(体积百分比)乙醇的水溶液中对邻菲罗啉和银离子间的络合进行了研究。实验结果表明确有络合反应存在,并测定了在25℃时在不同离子强度条件下,络合物的稳定常数。
In this paper, sodium ion-selective electrode was used to study the complexation between ortoporphyrins and silver ions in aqueous solution containing 30% (volume fraction) ethanol. The experimental results show that there is indeed a complexation reaction exists and the stability constant of the complex under different ionic strength conditions is measured at 25 ° C.
