本文报道在生理条件下稀土与 L-亮氨酸、L-天冬氨酸二元及三元体系的 pH 电位法研究数据.结果表明,随着稀土原子序数的升高(钇除外),二元及三元配合物积累稳定常数均缓慢增大,稀土离子主要是以荷电配合物形式存在.
In this paper, we report the data of pH-potential studies of binary systems and ternary systems of L-leucine and L-aspartic acid under physiological conditions. The results show that with the increase of rare earth atomic number (except for yttrium) The stability constants of element and ternary complex increase slowly, and rare earth ions mainly exist in the form of charged complexes.
