摘　　要：建立了微波消解—ICP-OES准确、快速测定皮革及其制品中多种重金属元素的分析方法。结果表明,优化微波消解条件和ICP-OES分析条件后,方法检出限(3S/N)为0.02～0.12mg/kg,3种浓度水平的加标回收率在91.1%～105.8%之间,相对标准偏差小于8.9%。该方法适用于皮革及其制品中重金属元素的日常检测。An effective method for determination of heavy metals in leather by ICP-OES with microwave digestion was developed in this paper. The results showed that the limit of detection （3S/N） was 0.02-0.12mg/kg, the average recoveries of heavy metals in leather at three levels ranged form 91.1%-105.8%, and the relative standard deviations were lower than 8.9% after microwave digestion and ICP-OES analytical condition were optimized. It has been applied to routine determination of heavy metals in leather with satisfactory results.
