摘要
污水处理厂污泥进行自然风干 ,筛分制备污泥样品 ,经烘干、硝酸 氢氟酸 高氯酸消解后 ,用火焰原子吸收光谱法测定污泥中铜、锌、铅、镉、镍含量。方法简便、快速、实用 ,具有较高的精密度和准确度。相对标准偏差为 0 .8%～ 6 .0 % ,加标回收率为 95 %～ 10 3%。
A method for the FAAS determination of Cu Zn Pb Cd and Ni in muddy soil is described. The muddy soil sample is digested with acid mixture of HNO 3-HF-HClO 4. The elements mentioned above are then determined by FAAS. The RSD′s of the method are found to be in the range 0.8%～6.0% and the recoveries are in the range 95%～103%.
