摘要
在 1.12mol/L的盐酸介质中 ,砷与钼酸铵生成砷钼蓝络合物。砷在 0～ 10 0 .0 μg/5 0 .0mL范围内符合比尔定律 ,λmax =84 0 .0nm ,ε =2 .30× 10 4。由此建立了利用分光光度法测定硫精矿中砷的方法。该方法用于硫精矿中砷的测定 。
In 1.12 mol/L HCl medium,arsonic contacts with ammonium molybdate to form arsenomolybdate blue complex.In the concentratoin range of 0～ 100.0 μm/50.0 mL, arsonic accords with Bill Law with λ max =840.0 nm and ε=2.30×10 4.Based on this, the new method for the direct determination of arsonic content in pyrite concentrate by spectrophotometry was proposed,which achieved satisfactory results when used in practice.
