  • 摘要: 利用连续萃取程序和加入外源化合物进行培养的方法,考察了土壤阳离子交换量(CEC)和土壤粘粒矿物含量的变化对土壤中钍形态分布的影响,随着CEC的增加,土壤中非残留态钍增加,而稳定态钍降低.随着土壤粘粒矿物含量的增加,土壤中残留态钍的含量明显增加,非残留态钍含量降低.
    Abstract: Accumulation,transfer and impact to environment of thorium are governed directly by fractions bound in soil.The thorium fractions in soil are affected by soil properties.The effects of cation exchange capacity(CEC)and clay content on the distribution of thorium fractions were investigated by sequential extraction pro-cedure and incubation of adding foreign compounds,and the reasons that the thorium fractions transferred with changes of CEC and clay content were discussed.Increase of CEC could enhance the content of non-residual fractions,however,reduce the content of stable fractions.Increase of clay content could enhance obviously stable fractions,meanwhile reduce non-residual fractions.

摘要: 利用连续萃取程序和加入外源化合物进行培养的方法,考察了土壤阳离子交换量(CEC)和土壤粘粒矿物含量的变化对土壤中钍形态分布的影响,随着CEC的增加,土壤中非残留态钍增加,而稳定态钍降低.随着土壤粘粒矿物含量的增加,土壤中残留态钍的含量明显增加,非残留态钍含量降低.
