摘要: Abstract There has been a trend towards the use of microorganisms to recover metals from industrial wastewater, for which various methods have reported be used improve microorganism adsorption characteristics such as absorption capacity, tolerance and reusability. In present study, chlorine dioxide(ClO2), high-efficiency, low toxicity environment-benign disinfectant, was first surface modification. The dioxide modified cells demonstrated 10.1% higher uranium capacity than control ones. FTIR analysis indicated that several cell groups are involved in were further immobilized on carboxymethylcellulose(CMC) matrix their cell-immobilized adsorbent could employed either high concentration system move vast UO 2 + ions or purify contaminated water thoroughly, repeatedly multiple adsorption-desorption cycles with about 90% maintained after seven cycles.
