摘　　要： 样品经过650~700℃灼烧除去有机物和硫,用王水分解,采用活性炭静态吸附的方法对其中的金、钯、铂进行富集。然后进行过滤,用稀王水、氟化氢铵热溶液、稀盐酸以及温水的洗涤滤饼除去铜、铁、铅等离子,通过灰化灼烧除去活性炭,用王水溶解合金粒,在稀王水介质中,用电感耦合等离子体发射光谱法直接测定金、钯、铂的含量。 The samples were decomposed by aqua regia after burning at the temperature of 650~700 ℃ to remove organics and sulfur. By using the method of active carbon static adsorption to enrich gold, palladium and platinum. Then filter, remove the copper ion, iron ion, lead ion by using dilute aqua regia, hot ammonium hydrogen fluoride solution, dilute hydrochloric acid and Warm water to Wash the filter cake. Burning the filter care to remove activated carbonstatic. Dissolving the alloy particles with aqua regia, then determine the gold, palladium and platinum by inductively coupled plasma emission spectrum in the dilute aqua regia medium.
