摘　　要：用固态膜铜离子选择性电极研究Ｆｅ（Ⅲ）与１，２－二羟基苯－３，５－二磺酸钠溶液配合物的组成和表观稳定常数．离于强度Ｉ＝０．１ｍｏｌ·Ｌ－１，ｐＨ＝２．１时生成１：１型配合物，ｐＨ＝３．０８时Ｆｅ（Ⅲ）与８－羟基喹啉生成１：１和１：２型两种溶液配位化合物．Cu-ISEs is used in this study to examine ferric-Tiron and ferric-oxine chelate compounds.It is found that a 1:1 complex fox finic-Tiron in PH=2.1and 1:1 and 1:2 complexes for ferric-oxine in PH=3.08 are formed.The composition and the apparent stability constants of these complexes can be calculated from the data of concentration cells with the potentionetric titration such as ourprevious work where ac is apparent complexion function.here
