Effect and influencing factors of modified biochar adsorption for the removal of nitrate nitrogen from water bodies

Nitrate-nitrogen pollution in water is a global problem. The research on the remediation technology of NO3 - -N polluted has become hot direction recent years. Biochar good adsorption effect nitrate nitrogen because its unique surface structure and rich properties. In this paper, basic properties biochar are introduced, progress modified for removal influencing factors summarized. problems shortcomings current field were analyzed, prospect using to remove pointed out.
