[Biosorption of Radionuclide Uranium by Deinococcus radiodurans].

As a biological adsorbent, Living Deinococcus radiodurans was used for removing radionuclide uranium in the aqueous solution. The effect factors on biosorption of radionuclide uranium were researched in the present paper, including solution pH values and initial uranium concentration. Meanwhile, the biosorption mechanism was researched by the method of FTIR and SEM/EDS.

[FTIR analysis of Sr2+ biosorption by Bacillus spp. strains isolated from soil treated with gamma-ray radiation].

One strain bacterium was isolated from purple soil of Sichuan basin. It was subject to Bacillus according to analysis results of 16S rDNA. The effect of its biosorption to Sr2+ under gamma-ray radiation was studied in this paper.

[Biosorption of lead ions on dried waste beer yeast and the analysis by FTIR].

The biosorption of lead ions on dried waste beer yeast was investigated with respect to the adsorption conditions and the biosorption mechanism was analyzed with the instruments of AAS, SEM/EDS and FTIR. The results show that the metal uptake value obtained was 47.6 mg x g(-1) and the adsorptive efficiency was above 90%.
