摘要
对镧系元素与磺基水杨酸(H_3SSA)络合物生成的条件进行了估算,用电位滴定的方法测定了MHL,M(HL)_2,ML和ML_2(M=镧系离子,L=SSA^(3-))络合物的稳定常数,并对它们随镧系原子序数的变化进行了讨论。
The complexation condition of lanthanide with sulfosalicylic acid is workedout roughly, and then the stability onstants of complexes, including MHL,M (HL)_2 ML and ML_2(M=lanthanide ions) are determined. The regularities ofthe stability constants with the number of lanthanide atoms are also discussed.
