MT/T 368-2005 《Determination of iron ion in coal mine water》 Related products

This standard specifies the determination of divalent and trivalent iron ions in coal mine water by o-phenanthroline Colorimetry, which is applicable to the determination of divalent and trivalent iron ions in coal mine water with a content of 0.25 to 8.00 mg/L. The content is obtained by Colorimetric determination by reducing trivalent iron ions to divalent iron ions under acidic conditions and forming a complex with o-phenanthroline. The required reagents, materials and instruments are listed, and the steps for mapping the working Linear dispersion are described.
