ABSTRACT

Humic acid-loaded biochar (HA-BC) remediation material is a new type of green soil conditioner. The composite material can effectively adsorb and fix naphthalene, an organic pollutant in polluted soil. Through UV-Vis, FT-IR, XPS and other characterization methods, the adsorption mechanism of humic acid-based remediation materials on naphthalene-contaminated soil was explored. The UV-Vis, FT-IR and XPS results showed that naphthalene formed intermolecular hydrogen bonds with the carboxyl groups of oxygen-containing functional groups in the humic acid-biochar material.
