Abstract: 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.
