在石油炼制工艺中,铂和钯常用来作为催化重整催化剂,加氢催化剂,一氧化碳助燃剂的活性组元,需要灵敏的分析方法。本文提出用石墨炉原子吸收(GFAAS)法测定催化剂中微量铂和钯的分析方法。用混合酸溶解样品,双十二烷基二硫代乙二酰胺(DDO)为络合剂,氯化亚锡为还原剂,在 In the oil refining process, platinum and palladium are commonly used as catalytic reforming catalysts, hydrogenation catalysts, and carbon monoxide combustion improvers, and require sensitive analytical methods. This paper presents a method for the determination of trace platinum and palladium in a catalyst by graphite furnace atomic absorption spectrometry (GFAAS). The sample was dissolved with a mixed acid, dodecyl dithioethane diamide (DDO) as a complexing agent, stannous chloride as a reducing agent,
