大肠杆菌JM109对废水中铀（VI）的吸附实验研究
Study on Adsorption Uranium(VI) in Water by Escherichia coli JM109
摘要
Abstract
Escherichia coli JM109 was used to adsorpt the low concentration uranium from wastewater in this paper. Also the adsorption efficiencies for this bacterium to uranium un-der the different influencing factors ( such as:pH value,temperature,adsorption time,the initial concentration of uranium, cell concentration, etc. ) were studied. The experimental results showed that U was favorable to be adsorbed by Escherichia coli JM109,especially to wastewater in low concentration of uranium. Optimum biosorption was observed when the solution pH was 4. 5,the adsorbent dosage of 0. 1 g/L and the adsorption equilibrium was established in about 50 min,the high adsorption capacity of 693. 8 mg/g. Isotherm study shows that the Freundlich adsorption model is better,and the kinetic model of Escherichia coli JM109 can be described to the pseudo-second-order model.关键词
