摘　　要： 硅酸盐中锆含量的测定方法较多,但应用分光光度法的报道很少。文章研究了适用范围广,灵敏度高,操作简单,线性范围较宽的偶氮胂Ⅲ光度法测定硅酸盐中锆含量。实验研究表明,在酸性介质(5-9MHCl)下测定的最佳吸收波长为665 nm,该方法稳定性好,灵敏度高,常规元素Na、K、Fe、Si、Ca影响较少,Ti、Mg、Al干扰较明显。 Many methods were used to determinate the Zr content in silicate, but the way application of spectrophotometry was few reported. The paper studied the determination of Zr by Arsenazo Ⅲ. The method had the advantages of wide application range, high sensitivity, simple operation, less interference, wide linear range in silicate. Experimental study showed that the methods of Arsenazo Ⅲ spectrophotometry was stable, sensitive. However, it was found that Ti, Mg, and Al were obvious interference on mensuration.
