钼酸铵——硫酸亚铁——碳酸钠比色定硅法

SPECTROPHOTOMETRIC DETERMINATION OF SILICON BY AMMONIUM MOLYBDATE-FERROUS SULFATE-SODIUM CARBONATE

本文建立了钼酸铵——硫酸亚铁——碳酸钠比色定硅法。该法简便易行,快速有效,不需特殊设备和试剂。由于不受磷酸根离子及维生素C等还原物质的干扰,故特别适用于生物材料及矿泉水等样品中水溶性硅的测定。

A method of silicon determination has been set up in this paper by ammonium molybdate—ferrous sulfate sodium carbonate spectrophotometry, which bears the advantages of simplicity .convenience,quickness and effectiveness, without the need of special equipments and reagents. Free of the influence of phosphate ion and reducing agents such as vitamin C and so on, this method is especially suitable to the determination of Silicon in biological meterials and mineral water.
