Research progress on biochar adsorption of soil organic pollutants
Biochar is a carbon rich material formed by the thermal decomposition of biological waste under low-temperature oxygen limiting conditions.It has unique surface chemical properties and complex pore structure,and has strong adsorption capacity for organic pollutants in environmental media.This article reviews the current situation and hazards of soil organic pollutant pollution,the preparation and advantageous characteristics of biochar,the adsorption mechanism of biochar,the factors affecting the adsorption of biochar on soil organic pollution,and the application of biochar in the remediation of organic contaminated soil.It also looks forward to the future research directions of biochar adsorption of soil organic pollutants.
