Preparation of Manganese Modified Biochar and Its Adsorption Performance on Methylene Blue
With corn cob as raw material and potassium acetate as activator,potassium acetate modified biochar(CCBC)and manganese loaded potassium acetate modified biochar(Mn-CCBC)were prepared by high temperature cracking method at 800℃,and the adsorption properties on methylene blue were investigated.The results show that Mn-CCBC has more abundant pore structure and larger specific surface area,and has better removal effect on methylene blue.Under the conditions of 25℃,adsorption time 60 min and initial mass concentration 30 mg/L,the removal rate of methylene blue could reach 99.594%.
