本文在前人的基础上,通过试验确定钪—钼—偶氮胂Ⅲ异金属三元络合物有较高的灵敏度(ε=4.46×10~4,灵敏度指数0.00101μg/cm~2)。在醋酸介质中有十七种金属元素共存时可直接测定钪。
Based on the previous studies, we determined the higher sensitivity (ε = 4.46 × 10 ~ 4, sensitivity index 0.00101μg / cm ~ 2) of scandium-molybdenum-arsenazo Ⅲ ternary complex by the experiment. Scandium can be directly measured in the presence of seventeen metallic elements in an acetic acid medium.
