摘　　要：利用原子荧光光谱法测定了浆层纸中的痕量汞.对酸度控制、仪器条件选择和硼氢化钾的用量等进行了研究,方法的检出限为0.083μg/L,精密度为1.1%,回收率为98.6%～105.3%.此方法的选择性好,灵敏度较高,获得的结果令人满意.The content of mercury in coated paper was determined by atomic fluorescence spectrometry. The domination of acidity, instrument conditions and concentration of potassium borohyride were investigated, The detection limit by the method was 0.083μg/L with relative standard deviation of 1.1% and recovery of 98.6% ～ 105.3%. The method was of high selectivity and sensitivity. The results obtained were satisfying.
