The Pseudomonas monteilii. YL-1 was cultured from deep sea sediment to remove uranium from aqueous solution. Different influence factors on uranium adsorption efficiency were investigated. The kinetic model of Pseudomonas monteilii could be described by the pseudo-second-order kinetic model, and the Freundlich isotherm model could fit the experiment data well, indicating that the adsorption was multilayer adsorption. The adsorption was spontaneous and endothermic reaction by thermodynamic analysis. The functional groups of Pseudomonas monteilii such as hydroxy, carboxyl, amino and amide may act with UO2 (2+) by chemisorption or strong complexation in the process of uranium adsorption.
