| 摘 要： | 以某硫酸企业含砷污泥为研究对象,采用现行的浸取方法处理该含砷污泥,并用原子荧光光谱法和火焰原子吸收分光光度法测定其浸出液中的砷和铅、镉、铜、锌等5种重金属含量.结果表明,含砷污泥中砷、铅、镉、铜4种重金属含量均存在超标现象,相对标准偏差在81.1%～103.5%之间,加标回收率在0.05%～0.64%之间.此分析方法简... |

| Abstract: | The arsenic sludge taken from a sulfuric acid enterprise was treated with the current method,then contents of five kinds of heavy metal arsenic,lead,codmium,copper,zinc,which were contained in its leaching solution,were determined by atomic fluorescence spectrometry and flame atomic absorption spectrophotometry.The results showed that,contents of four heavy metals including arsenil,lead,codmium,copper were over the limit.The relative standard deviations were 0.05%~0.64%,and the recoveries were 81.1%~103.5%.This analysis method is simple,sensitive,accurate and suitable for determination of heavy metal content of arsenic sludge and other solid industrial wastes of sulfuric acid industry. |
| Keywords: | sulfuric acid industry arsenic sludge heavy metal content determination |
