GB/T 1879-1995 《Phosphate rock and concentrate--Determination of potassium oxide content--Flame atomic absorptionspectrometric method》 Related products

The GB/T 1879-1995 standard specifies a method for the determination of oxidation potassium content in phosphate rock and phosphate concentrate ore by flame atomic absorption spectroscopy (AAS). The standard applies to the analysis of phosphate rock and phosphate concentrate ore with oxidation potassium content greater than 0.1%. The content of potassium oxidation is determined by inhibiting phosphoric acid root interference by adding manganese salts and using acetylene-air flame measurement of the sample in a dilute muriatic acid medium. The standard provides an accurate analytical method for mass testing of phosphate rock and phosphate concentrate ore products, ensuring that the products meet industrial requirements.
