GB/T 34176-2017 《Chemical analysis methods for determination of Fe2+ and Fe3+ in refractory products by the spectral photometric method with 1,10-phenanthroline》 Related products

GB/T 34176-2017 stipulates the chemical analysis method for the determination of divalent and trivalent iron ions in refractory materials by o-phenanthrene Spectrophotometric method, spectrophotometry. The standard specifies the reagents and instruments required for the experiment, and elaborates the Sample Handling steps in detail, including sample dissolving, interference ion elimination, etc. Through the color reaction of o-phenanthrene and iron ions, the spectrophotometer is used to measure Absorbance, so as to accurately determine the content of Fe ² and Fe ³ in refractory materials. The standard provides reliable analytical means for refractory production and mass detection, helps to control product mass, and promotes the standardization of the industry.
