This part of SN/T 2763 specifies methods for the determination of nickel, calcium, titanium, manganese, copper, cobalt, chromium, zinc and phosphorus in laterite nickel ores using Inductance Coupled Plasma Atomic Emission Spectroscopy (AES). This method is applicable to the determination of the content of these elements in laterite nickel ores. By citing documents such as GB/T 602, GB/T 6682 and GB/T 23942, the specifications and test methods for laboratory water are determined, as well as the general rules for the preparation of chemical reagents and Inductance Coupled Plasma Atomic Emission Spectroscopy (AES). The method summary includes the analysis, dissolving and determination steps of the sample.
