This standard specifies the method for the determination of lead, arsenic, titanium, copper, nickel, calcium, mg, aluminum content in ferromanganese, manganese silicon alloy, and metal manganese by Inductance Coupled Plasma Atomic Emission Spectroscopy (AES). Applicable to the determination of each element in these materials, the determination range is detailed in Table 1. The normative reference documents include GB/T 4010, GB/T 6379.1, GB/T 6379.2, GB/T 6682, etc. The principle of the method involves the analysis, conversion, measurement and calculation of the sample. The reagent should be analytically pure and meet the relevant water quality requirements. Warning users to have laboratory work experience, to take safety and health measures, and to comply with relevant regulations.
