| Abstract: | A strain of bacterium cupric ion tolerant was screened from electroplating sludge and wastewater, it can live in Cu 2+ concentration of 560mg/L, according to bacterial individual shape and colony shape and physiological biochemical characters, it was identified Pseudomonas aeruginosa . The optimal adsorption conditions of Cu 2+ by strain pH=5.0, contact time=0.5h, speed of shake bed =50r/min, amount of bacteria=100mg were obtained by orthogonal test. In optimal conditions, the adsorption capacity of bacteria is 14.68mg/g. |
