Application Summary AI generated

This standard specifies a photometric method using 2,9-dimethyl-1,10-phenanthroline (neocuproine) to determine the cupric oxide (CuO) content in alumina. It is applied in the metallurgical industry, particularly for quality control of smelter-grade alumina used in aluminum production, where trace copper levels must be monitored to ensure product purity and process performance.
