ActiveIron ores—Determination of arsenic content—Arseno-molybdenum blue spectrophotometric method after the distillation separation
铁矿石 砷含量的测定 蒸馏分离-砷钼蓝分光光度法
Application Summary AI generated
This standard specifies the arseno-molybdenum blue spectrophotometric method for determining arsenic content in iron ores, following distillation separation to remove interferences. It is applied in the mining and metallurgical industries for quality control of iron ore products, particularly during ore processing, trading, and smelting operations. The method is used in laboratory testing contexts to ensure arsenic levels meet regulatory and industrial specifications for steel production.
