等离子全谱测定铬铁矿中TFe_2O_3、Al_2O_3、CaO等物质含量

采用ICP-AES对铬铁矿试样用氢氟酸一硫酸分解,除去硅,直接测定其中TFe2O3、Al2O3、CaO等十二种元素的含23量,可达到快速测定的目的。

Uses ICP-AES to the chromite test specimen with a hydrofluoric acid sulfuric acid decomposition, except the silicon, immediate determinant TFe2O3, Al2O3, CaO and so on 12 kind of element＇s content, may achieve the fast determination the goal.
