摘　　要：建立了一次性餐具中砷的氢化物发生 -原子荧光测定方法 ,在选定的试验条件下 ,荧光强度与砷质量浓度在0 μg/L～ 180 μg/L范围内呈线性关系 ,相关系数 0 9993,溶液检测限 0 5 μg/L ,回收率 96 %～ 10 1%Atomic fluorescence spectrometry for the determination of arsenic in single used table wares was established. Under the selected experiment conditions,there was a linear relationship between the fluorescence intensity and arsenic concentration in the range of 0～180μg/L with correlation coefficient of 0.999 3,the detection limit was as low as 0.5 μg/L,and the recovery was 96%～101%.
