This standard specifies a method for the determination of total nickel, total cobalt, total selenium, total vanadium, total antimony and total thallium in fertilizers by Inductance Coupled Plasma Emission Light Spectrometry (ICP-OES), which is suitable for the detection of these elements in various fertilizers. The standard describes in detail the pretreatment process of the sample, the operation requirements of the instrument and equipment, the analysis method, the calculation of the results, and the detection limit and precision. The standard provides a scientific basis for the quality control and security evaluation of trace elements in fertilizers.
