摘要:
用pH电位法研究Th(NO3)4和乙二胺四乙酸二钠盐分别与d-缬氨酸、dl-异亮氨酸、dl-蛋氨酸、l-谷氨酰胺、l-脯氨酸在水溶液中的配合反应.证明在pH=5~6时,有1∶1∶1的ThYL(L-氨基酸根,Y-乙二胺四乙酸根)混合配合物生成,在(30±0.1)℃ ,离子强度μ(KNO3)=0.15的条件下,测定了相应配合物的稳定常数 .除[ThY (l-Pro)]-外,其余 与 呈 =1.40l -8.30线性关系.
Abstract:
The complex reactions of Th(NO3)4 and complexon III with d-valine,dl-isoleucine,dl-methionine,l-amide glutamate and l-proline in water solution have been respectively investigated using the pH potential method.It is demonstrated that the complex compound of ThYL (L-root of amino acid,Y-root of EDTA)with the ratio of 1∶1∶1 is formed when pH=5~6.The stability constant has been measured under the conditions of 30±0.1℃and ionic strength μ(KNO3)=0.15.There exists the following linear relationship between and : =1.40 -8.30,except [ThY(l-Pro)]-.
