Application Summary AI generated

This standard specifies the thiourea preconcentration and catalytic polarographic method for determining platinum and rhodium content in geochemical samples. It is applied in geological exploration and mining industries for analyzing trace amounts of these noble metals in ores, rocks, and soil samples. The method is particularly used for environmental monitoring and resource assessment where high sensitivity detection of platinum group elements is required.
