| Abstract: | The paper discussed the effects of rice bran charcoal dosage, solution temperature, Cd2＋ concentration, pH value and adsorption time for rice bran charcoal to adsorb Cd2＋. The results showed that rice bran charcoal have good adsorption performance on Cd2＋ with an adsorption rate of 94.6%. Its best adsorption conditions were rice bran charcoal dosage 20 g/L, solution temperature 30 ℃, pH value 3, Cd2＋ concentration below 50 mg/L and adsorption equilibrium time 30 min. |
