Preparation and Modification of Rape Straw Biochar and Its Adsorption Characteristics for Methylene Blue in Water

To solve the double problems of methylene blue (MB) pollution in water and waste of straw resources, rape straw biochar (RSB600) was made by thermal decomposition of discarded rape residues at 600 °C, and modified RSB600(M-RSB600) was prepared after treatment with NaOH for MB adsorption. The physico...
