| 摘 要： | 采用NHO3＋HF＋H2O2体系微波消解垃圾焚烧飞灰，火焰原子吸收光谱法测定金属Cu，Fe，Pb，Ni，Mn，Cr和Cd的含量。结果表明，飞灰中Cu质量分数为0．8927mg／g，Pb质量分数为1．8490mg／g，Ni质量分数为0．1523mg／g，Mn质量分数为1．1033mg/g，Fe质量分数为86．4517mg／g，Cr质量分数为0．3667mg／g，Cd质量分数为0．0581mg／g。铁的检测限为3．9041mg／L，其它元素均小于1mg／L，加标回收率在98．0％-108．0％之间。RSD〈4．0％。该法简便快速，具有较好的准确度和精密度，测定结果为处理垃圾焚烧所产生的飞灰提供了理论依据。
