The GB/T 18114.5-2010 standard specifies a method for the determination of aluminum oxide in rare earth concentrates. The method uses Inductance Coupled Plasma Emission Light Spectrometry (ICP-OES) to melt and analyze samples by sodiumhydrate and sodium peroxide. After alkali separation, rare earths and thorium are removed, and Matrix effect correction is performed in acidic solution. The determination range is 0.50% to 8.00%. The standard describes the preparation of reagents and instrumentation requirements in detail, including argon purity and the configuration of Light spectrum instrument, which provides a technical basis for accurate determination of aluminum oxide.
