日立150-20型分光光度计测定微量及高含量Fe_(2)O_(3)

Determination of Fe_(2)O_(3) of Major to Minor Amounts by a Single Photometric Procedure

使用标尺读数的分光光度计(如国产72型,751型等)磺基水杨酸测定铁时,只能测定含量为0.05~5%的样品。对高含量的样品也可采用差示法测定,但须配制与待测试液含量相近的标准试液来测定。

The procedure is useful for the determination of Fe_(2)O_(3) in the range 0-100%. A Hitachi 150-20 spectrophotometer was used at two different wavelengths, using sulphosalicylic acid as the color reagent.
