摘要
对羧基偶氮氯膦及其与钇络合物的光化学、电化学性能研究卢燕曲连家杨茹ＣＰＡｐＫ是七元酸，随溶液碱性的增加，试剂逐级离解，第１～５级离解分别为两个ＳＯ３Ｈ及一个ＰＯ３Ｈ２、一个ＣＯＯＨ中Ｈ＋的离解，第六、七级离解为萘环上两个羟基中Ｈ＋的离解，本实验测定ｎ...
Optics and electrochemistry properties of CPApK and the complex with yttrium (Y) were discussed.The protonation constant (2 233),the protonation number (1), the dissociation constant(9 877) were determined.CPApK and the complex with Y (CPApK∶Y=2∶1)have absorptive property on mercury electrode.The reaction of reduction between them is unreversible reaction and produce polarographic adsorptive wave.
