The present paper is to introduce our study of the biosorption of uranium by Deinococcus radiodurans,the effect of pH,contact time,the initial U(Ⅵ) concentration,the concentration of D.radiodurans,as well as the various pretreatment procedures on the biosorption in addition to the desorption efficiency were studied.The results of our research have shown that the maximal adsorption quantity can reach 48.62 mg/g with the optimal pH value being 4.0.The absorption rate can be expected to reach 95.12% when the a...
