通过HF—HClO4-HNO3混合酸消解法对廊坊市生活垃圾处理场生成的可以作为有机复混肥底肥的垃圾粉肥样品进行了前处理，采用火焰原子吸收光谱法测定其中铜、锌、铅元素的含量，对样品前处理条件进行了优化选择。该法溶样完全，测定手续简便快速、干扰小，具有较高的准确性和精密度。各元素的相对标准偏差为：Cu1．02％，Zn1．92％，Pb3．24％：同收率为：Cu95．27％～104．9％，Zn94．60％～107．9％。Pb94．74％～104．6％。用加标回收率和国标物测定，结果均令人满意。

A method for the flame atomic absorption spectrophotometer （FAAS） determination of Cu Zn and Pb in rubbish mixed fertilizer was described. The rubbish mixed fertilizer sample was digested with acid mixture of HF-HClO4-HNO3. The operating conditions were optimized before the detection. This method had the advantages of disslovling sample wholly, convenient operation, small disturbance, and high accuracy and precision. The relative standard deviations （RSD） of Cu, Zn, Pb were 1.02 %, 1.92 %, 3.24 and the recovery rates were 95.27 %-104.9 %, 94.60 %-107.9 %, 94.74 %-104.6 %, respectively. The result is satisfactory.
