用偶氮肿Ⅲ试剂比色测定钪,在国外资料上早有报导。国内似未见刊载。试验证明,灵敏度和选择性(尤其是选择性)皆优于常用的显色剂茜素磺酸钠以及二甲酚橙。本文拟就该试剂比色测定钪的有关问题暨钨精矿中测定钪的方法予以报导。
Determination of scandium with azo-swollen Ⅲ reagent colorimetric has long been reported in foreign data. There seems to be no domestic publication. Tests have shown that the sensitivity and selectivity (especially selectivity) are superior to the commonly used color reagent sodium alizarin sulfonate and xylenol orange. This article intends to colorimetric reagent determination of scandium-related problems and determination of scandium in tungsten concentrate methods are reported.
