| Abstract: | Microbial fermentation of rice bran was applied to absorbing Cd2＋.The effects of the dosage of adsorption,solution temperature,Cd2＋ concentration,pH value,adsorption time on adsorbing Cd2＋ were discussed.The research result showed microbial fermentation of rice bran had good adsorption to Cd2＋,and the adsorptive rate reached 93.8%.Its best adsorption conditions were the dosage of microbial fermentation of rice bran 20 g/L,solution temperature 30℃,pH=3,Cd2＋ concentration below 50 mg/L,and adsorption equilibrium time 60 min. |
