| Abstract: | 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%. |
