求翻譯，幫者有份，重金屬形態(tài)測定
|
|
|
采用BCR提取法對以污泥和花生殼為原料制備的活性炭進(jìn)行重金屬形態(tài)分析，利用原子吸收法測定污泥熱解前后Cd、Cr、Cu、Zn、Ni、Pb的四種不同形態(tài)含量。 結(jié)果表明熱解能使重金屬由易遷移的酸溶態(tài)和可還原態(tài)轉(zhuǎn)化為性質(zhì)穩(wěn)定的殘?jiān)鼞B(tài)，同時(shí)得出花生殼的添加量增加，重金屬殘?jiān)鼞B(tài)略微減少；綜合各種重金屬的穩(wěn)定態(tài)比例，得出在600度下相對穩(wěn)定。 |

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. 僅供LZ參考。 |

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. 結(jié)果表明熱解能使重金屬由易遷移的酸溶態(tài)和可還原態(tài)轉(zhuǎn)化為性質(zhì)穩(wěn)定的殘?jiān)鼞B(tài)，同時(shí)得出花生殼的添加量增加，重金屬殘?jiān)鼞B(tài)略微減少；綜合各種重金屬的穩(wěn)定態(tài)比例，得出在600度下相對穩(wěn)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. |
