原子吸收法测定垃圾堆肥中重金属铜、铁、锰、铅、铬的含量

Determination of Heavy Metal in Refuse Compost by Flame Atomic Absorption Spectroscopy

用火焰原子吸收光谱法对遵义欣环垃圾公司生产的垃圾堆肥中铜、铁、锰、铅、铬的含量进行了测定,实验结果表明,方法的选择性较好,线性范围宽,标准曲线相关系数为0.9994—0.9997,该垃圾堆肥显碱性且重金属的含量普遍偏高。

Flame tomic absorption spectroscopy was made to determine the content of copper,iron,manganese,lead,and chromium in refuse compost in Xinhuan garbage of Zunyi.The findings are as follows： it has a good selectivity and a wide linear scope,with the correlation coefficient of the standard curve ranging from 0.9994 to 0.9997;and the fine compost assumes alkaline;besides,its content of heavy metal is a little high.
