摘要
用批式实验法研究了放射性^(99)TcO_4^-在含锑矿物上的吸附行为和各种影响吸附能力的因素,并对吸附机理进行了讨论。研究结果表明,放射性锝在含锑矿物上的吸附过程基本为氧化还原吸附,吸附能力受多种因素的影响,吸附等温线不能很好地符合Freundlich吸附等温线。
In this paper, the sorption behaviours of radioactive technetium on such antimony-containing minerals as antimonite have been studied with the batch experiment,and the effects of the pH value, temperature,the particle size,etc. on the sorption ratio have also been investigated. The results show that the sorption capacity is very high and is influenced by many factors,the adsorption isotherm on antimonite does not fit the Freundlich adsorption isotherm very well.
