The GB/T 24193-2009 standard specifies a method for the determination of aluminum, iron, mg and silicon content in chromium ores and chromium concentrates using the Inductance Coupled Plasma Atomic Emission Spectroscopy (AES) method (ICP-AES). The standard applies to the detection of aluminum, iron, mg and silicon concentrations in these ores. The method involves using a molten sample of sodium peroxide, leaching with muriatic acid, and diluting the solution to a certain volume. Afterwards, the solution is atomized by a high salt resistant Nebulizer and introduced into the Inductance Coupled Plasma for analysis. The emission Light spectrum intensity of each element is determined and the concentration is calculated by calibrating Linear dispersion. This process ensures the accuracy and Reliability of the measurement results.
