GB/T 23524-2019 "Petrochemicals Waste Platinum Catalyst Chemical Analysis Method, Determination of Platinum Content Inductance Coupled Plasma Atomic Emission Spectroscopy (AES) Method" standard specifies a method for the determination of platinum content in Petrochemicals aluminum-silicon carrier waste platinum catalyst. The standard is applicable to samples with platinum content ranging from 0.100% to 0.800%. After the sample is treated with reagents such as sulfuric acid, muriatic acid and sodium chlorate, the Inductance Coupled Plasma Atomic EmissionSpectrometer is used for the determination of platinum content in waste platinum catalysts. This standard provides a technical basis for the accurate analysis of platinum content in waste platinum catalysts.
