用Ｅ（％）－ｐＨ曲线法实验研究了海水中三元表面络合物的形成和构型。通过海水中金属铜离子对氨基酸—粘土界面作用的Ｅ（％）－ｐＨ曲线影响的研究，发现曲线具有“单向上移”的规律，表明甘氨酸、天冬氨酸—铜离子—高岭土三元体系在实验条件下主要形成（Ⅰ）型三元表面络合物即≡Ｓ—Ｏ—Ｍ—Ｌ。该系列论文另一部分已研究氨基酸对金属离子—粘土体系的影响，证明可形成（Ⅱ）型三元表面络合物即≡Ｓ—Ｏ—Ｌ—Ｍ。据此可以推测（Ⅰ）型和（Ⅱ）型在某一条件下可以转变构型，其中间构型可能即是Ｌｅｃｋｉｅ等提出的环形三元表面络合物。
The formation and configuration of ternary surface complexes in seawater were investigated by E (%) - pH curve method. Through the study of the effect of metal copper ion on the amino acid-clay interface in seawater, we find that the curve has the tendency of “one-way up-shift”, indicating that glycine, aspartate-copper ion-kaolin ternary system Under the experimental conditions, the ternary complex (≡S-O-M-L) mainly forms. Another part of this series of papers has studied the effect of amino acids on the metal ion-clay system, demonstrating that a ternary complex of the type (II), ie, ≡S-O-L-M, can be formed. It can be inferred that the (Ⅰ) and (Ⅱ) transitions can be made under certain conditions, and the intermediate configuration may be the ring ternary complex proposed by Leckie et al.
