| 摘 要： | 在微酸性溶液中钪与甘氨酸邻甲酚红(GCR)和溴化十六烷基三甲铵(CTMAB)形成红紫色的三元络合物。在其最大吸收波长540nm处的表观摩尔吸光系数为4.14×104。三元络合物的络合比为SC:GCR:CTMAB=1:2:2。当以乙酰丙酮及邻菲啰啉为联合掩蔽剂时,大量稀土元素及10余种共存元素不干扰钪的测定。用本法测定了合成的混合稀土样品中的少量钪,得到了较满意的结果。

| Abstract: | A red-violet ternary complex of scandium with GCR and CTMAB is formed in a weak acid solution. The maximum absorption. of the ternary complex is at 540nm with apparent molar absorption coefficient of 4.14?104. The composition of ternary complex is found as: Sc:GCR:CTMAB=1:2:2. For the Sc dertermination the interfreences of the diverse ions was reduced by masking with a mixture of acetylaceton and phenanthroline.The method has been used satisfactorily to determine small amount of Sc in the synthetic mixture of rare earths. |
