摘要
采用方便、快速的砷斑法测定铬酐中微量砷元素 ,最低检出量为 0 .5× 1 0 - 6( m/m) ,适用于铬盐生产的中控分析和质量检验。
Micro-arsenium in chromic anhydride is determinated by arsenic stain method easily and quickly.The lowest detection limit is 0.5×10 -6 (m/m).This method is applied to intermidiate analysis and quality test on the production of chromic anhydride.
