GB/T 11066.8-2009
ActiveMethod for chemical analysis of gold - Determination of silver, copper, iron, lead, antimony, bismuth, palladium, magnesium, nickel, manganese and chromium content - Ethyl acetate extration-inductively coupled plasma - Atomic emission spectrometry
金化学分析方法 银、铜、铁、铅、锑、铋、钯、镁、镍、锰和铬量的测定 乙酸乙酯萃取-电感耦合等离子体原子发射光谱法
Application Summary AI generated
This standard specifies the use of ethyl acetate extraction combined with inductively coupled plasma atomic emission spectrometry (ICP-AES) to determine the content of eleven trace impurity elements in gold. It is applied in the metallurgical industry for quality control and certification of refined gold, particularly in bullion, jewelry alloys, and gold anodes used in electroplating. The method ensures compliance with purity specifications by detecting contaminants that affect electrical conductivity, mechanical properties, or corrosion resistance.
