| Abstract: | In order to improve the purification effect of Uranium containing waste water, we prepared a kind of new magnetic composite biological adsorbent, which was used to study the adsorption behavior of uranium ion. The adsorbent were characterized by BET, IR, XRD and SEM, the adsorption kinetics was studied. The results showed that the optimum conditions were as follows: the mass ratio of Fe3O4 and Saccharomyces cerevisiae was 1:2, the pH value of the solution was 5, the amount of adsorbent was 0.05 g, the initial concentration was 60 mg/L, and the shaking time was 2 h. The best adsorption rate was 82.41%, the unit adsorption capacity was 29.76 mg/g, the pseudo first order kinetic equation was y=0.3882x + 0.6089, R2=0.9306, and the linear relationship was good and the surface activity of adsorbent is high. |
