摘要
研究了稀土元素铈(Ⅲ)离子与3,4-二羟基苯甲酸(H3L)在水溶液体系中生成羧基配位化合物的条件,表征其组成为Ce(H2L)2(OH)·3H2O,并研究了该配合物在一定条件下,铈离子由羧基配位反应变为由两个邻酚羟基配位的配合物[Ce(HL)n]的转型反应及氧化成铈(Ⅳ)配合物的反应.
The complex of cerium(Ⅲ) with 3,4 dihydroxybenzoic acid was prepared in aqueous solution of pH=5.6~9.0, and the formula Ce(H 2L) 2(OH)·3H 2O was determined by means of IR, TG DTA and elementary analysis. In alkaline aqueous solution, the cerium cation of the complex can be transformed from carboxyl group to dihydroxyl group in the same ligand and formed a new chalation compound.
