| Abstract: | The removal of Cd2+ in aqueous solution is investigated by using marble in this paper.We find that marble can remove Cd2+ from aqueous solution effectively.The main influence parameters in this experiment are solution pH,contact time,initial cadmium concentration and marble addition.In the condition of pH=8,marble addition=12.5 g/L,contact time=30 mins and Cd2+ initial concentration=50 mg/L,the removal rate of cadmium is 92%,the cadmiumadsorption capacity is 3.68 mg/g.Typical adsorption isotherms are calculated,and the Langmuir type is best. |
