GB/T 13551-1995 is a standard for the detection of phosphate rock and phosphate concentrate. It explicitly uses flame atomic absorption spectroscopy (AAS) to accurately determine the content of cadmium oxidation. Cadmium oxidation is toxic, and its content in phosphate rock and phosphate concentrate not only affects the mass of the product, but also affects the safety of subsequent processing and application. This standard provides relevant enterprises and testing institutions with a standardized and unified detection method, which helps to strictly control the mass of phosphate rock products and ensure the safety of production and use.
