摘要
用静态实验法研究了锝在格列土上的吸附行为。观察了葡萄糖、NaOH和腐殖酸对得在格列土上吸附比(Rd)的影响。结果表明,格列土比一般地表土(砂土、凝灰岩土等)对锝有更大的吸附比;微生物活动能够阻滞碍的迁移;腐殖酸对吸附的影响不大;NaOH可以增加格列土对锝的阻滞能力。
The sorption behaviour of technetium on gley soil is studied by batch experiment.The effects of additions of dextose (in order to activate the microbial activity),NaOH and humic acid on the sorption of Tc by gley soil have also been investigated.The results show that the sorption ratio of Tc on gley soil is higher than that on ordinary surface soils(for example:sand and tuff),the mi crobial acivity and the addition of NaOH have great influence on sorption of Tc on gley soil,whereas the addition of humic acid has little effect on sorption behaviour.
