摘要
采用硝酸/盐酸/水消解体系进行微波消解,运用双道原子荧光分析法分析鞋材中的砷含量。结果表明该方法的检出限为0.032mg/kg,回收率为93.7%～112%,精密度(相对标准偏差,RSD)小于3%。该方法具有操作简单、快速,灵敏度高,精密度好等特点。
Shoe material was digested by microwave digestion system, with nitric acid/hydrochloric acid/ water as digestion solution, and arsenic content of digested material was analyzed using dual-channel atomic fluorescence spectrum. The results indicated that the aforementioned method is simple, rapid, and with high sensitivity and precision in the determination of arsenic content in shoe material, with detection limit of 0.32 mg/kg, sample recovery of 93.7%-112%, and precision （presented as relative standard deviation） less than 3%.
