Abstract
N,N'-oxalylbis(salicylaldehyde hydrazone), N,N'-malonylbis(salicylaldehyde hydrazone), and N,N'-succinylbis(salicylaldehyde hydrazone)과 Cd(Ⅱ) 이온과의 착물형성에 따르는 안정도상수를 DMSO 용액에서 폴라로그래피법으로 측정하였다. 안정도상수의 크기는 OBSHThe complexation of hydrazide schiff base ligands such as N,N'-oxalylbis(salicylaldehyde hydrazone), N,N'-malonylbis(salicylaldehyde hydrazone), and N,N'-succinylbis(salicylaldehyde hydrazone) with Cd(Ⅱ) ion was studied by polarographic method in DMSO solution. The order of stability constants was OBSH < MBSH < SBSH, and these ligands formed stable complexes with Cd(Ⅱ) ion. The stability constants of complexation were measured at various temperatures. As the results, △H and △S of the complexation were distributed on the complex stabilities.
