微生物的用途，包括活的和死的细菌生物量，如放线菌，已被广泛研究。在目前的工作中，提出了浮选作为分离阶段收获悬浮微生物生物吸附镉。在分批模式下研究的参数是溶液pH值，离子强度，使用的起泡剂（乙醇）和阳离子收集剂（十六烷基三甲基溴化铵）和生物量洗脱EDTA。并与镉离子浮选法进行了比较。在稀镉水溶液中用死链霉菌生物质获得了有希望的结果。
The uses of microorganisms, including live and dead bacterial biomass such as the actinomycetes, have been widely studied. In the present work flotation is proposed as the separation stage for harvesting suspended microorganisms following biosorption of cadmium. The parameters investigated in batch mode were solution pH, ionic strength, use of a frother (ethanol) and a cationic collector (cetyl trimethylammonium bromide) and biomass elution by EDTA. The process was also compared with cadmium ion flotation. Promising results were obtained with deadStreptomycesbiomass in dilute aqueous cadmium solutions.
