求翻译，帮者有份，重金属形态测定
|
||
|
采用BCR提取法对以污泥和花生壳为原料制备的活性炭进行重金属形态分析，利用原子吸收法测定污泥热解前后Cd、Cr、Cu、Zn、Ni、Pb的四种不同形态含量。 结果表明热解能使重金属由易迁移的酸溶态和可还原态转化为性质稳定的残渣态，同时得出花生壳的添加量增加，重金属残渣态略微减少；综合各种重金属的稳定态比例，得出在600度下相对稳定。 |

采用BCR提取法对以污泥和花生壳为原料制备的活性炭进行重金属形态分析，利用原子吸收法测定污泥热解前后Cd、Cr、Cu、Zn、Ni、Pb的四种不同形态含量。 The mophological analysis of heavy metals had been carried out by BCR extraction method in activated carbon made of sludge and peanut shell. The content of Cd, Cr, Cu, Zn, Ni and Pb with four mophological states before and after sludge pyrolyzing had been measured using atomic absorption method. 结果表明热解能使重金属由易迁移的酸溶态和可还原态转化为性质稳定的残渣态，同时得出花生壳的添加量增加，重金属残渣态略微减少；综合各种重金属的稳定态比例，得出在600度下相对稳定。 The results showed that the pyrolyzation process can transform the heavy metals from migratable acidic soluble state into property stable residual state. As the additive amount of peanut shell increase, the content of heavy metal residual state decrease slightly. With comprehensive comparation of various stable state ratios of heavy metal, it was obtained that the relative stable pyrolyzation temperature is 600 degree celsius. |

This paper analyses heavy metal foems using BCR method for activated carbon developed from sludge and peanut shell and determines the content of different forms elements,Cd, Cr, Cu, Zn, Ni, Pb,before and after pyrolysis by AAS(Atomic Absorption Spectrometry). The results indicated that the pyrolysis would transform heavy metal from easily migratory acid-soluble form and reducible form into stable residual state, and that if peanut shells increased, heavy metal residual form would slightly reduce.Studying on the various stable form proportions of heavy metal, the conclusion are drawn that these heavy metal will keep relatively stable in 600 degrees. 仅供LZ参考。 |
