Preparation and modification of biomass carbon and research of the adsorption of copper

With the acceleration of industrialization, industrial wastewater discharge makes environmental pollution more serious. How to deal with industrial wastewater has attracted more and more attention. It is a good method to deal with copper in wastewater by using biomass activated carbon. In this study, biomass carbon (AC) was prepared from corn stover as raw material. Preparation of nitrogen-containing biomass carbon (AC-N) using melamine as nitrogen source. Preparation of iron-loaded biomass carbon (AC-Fe) and iron-nitrogen-loaded iron biomass carbon (AC-N-Fe) using AC and AC-N as carriers and ferric nitrate as iron source. Choosing the different concentrations, temperatures, adsorption times to explore the adsorption properties of different carbons on copper ions. The results show that the adsorption performance of modified biomass carbon on copper is much greater than that of the original carbon (AC), and the modification is effective. (paper)
