- Аннотация: The effectiveness of lanthanum, chromium, uranium, and vanadium ion bioaccumulation and time-dependent biosorption from single- and multi-component systems by bacteria Pseudomonas putida was studied. The process of metal uptake was traced using reactor neutron activation analysis. In the experiment on accumulation, the efficiency of metal uptake was observed as follows: La > U > Cr > V (single-metal system) and U > Cr > La > V (multi-metal system). In the 2-h biosorption experiments, the highest rate of metal biosorption was noticed for chromium and uranium in single-component systems, and for uranium and vanadium in multi-metal system. Pseudo-first-order Lagergren model was applied when simulating the kinetic experiment results. Fourier transform infrared spectroscopy was used to identify the functional groups responsible for metal binding. The results of the present work have shown that Pseudomonas putida biomass can be efficiently implemented for industrial effluents treatment.
