依据磷、硅、砷和钼酸盐形成的杂多酸被还原剂还原的反应速率不同,建立了同时测定此3个元素的动力学分光光度法.本法成功地应用于生铁样中微量磷、砷、硅的同时测定,结果满意.
The kinetic spectrophotometric method for the simultaneous determination of these three elements was established based on the different reaction rates of heteropolyacids formed from phosphorus, silicon, arsenic and molybdate reduced by reducing agents.This method was successfully applied to the determination of trace phosphorus , Arsenic, silicon simultaneous determination, the results are satisfactory.
