GB/T 23524-2009 Focused on the determination of platinum content in waste catalysts of Petrochemicals, using Inductance coupled plasma atomic emission spectroscopy (AES) method. The standard describes the determination principle, specifies the required equipment and reagents, and details the whole process from sample collection and processing to instrument measurement of waste catalysts, including sample digestion, solution preparation, calibrated Linear dispersion drawing and measurement operations. With this standard, the platinum content in waste catalysts can be accurately determined, which helps resource recovery and utilization, provides a basis for production control and cost accounting of related enterprises, and promotes industry standardization testing.
