摘要
用ICP -ABS手动扫描光电测定硫酸钛白母液中微量钪 ,考察了基体及硫酸的存在对钪发射强度的影响 ,并采用标准加入法扣除样品基体的影响。本法无需经过分离、富集等预处理 ,方法简便、快速。
This paper described the method for the manual-scanning photoelectric determination of trace scandium in sulphuric acid titanium white liquor by ICP-AES.The effects of matrix and sulphuric acid for emission intensity of scandium were investigated,and removed the effect of sample matrix by calibration added.It needs no separation and enrichment.The method is simple and rapid.
