Abstract

Abstract

Biochar derived from sewage sludge is widely used for the treatment of various environmental contaminants. However, little is known about the effects of the biochar on remediation of Cr contaminated soil. In this study, the effects and mechanisms of the biochar prepared via co-pyrolysis of sewage sludge and cotton stalks on the immobilization of Cr in a sandy loam soil (Cr, 33.9 mg/kg) were investigated. The Cr content increased from 34.0 mg/kg to 38.5 mg/kg with the addition ratio increasing from 1% to 15%. The contents of Cr in all treatments were lower than the thresholds of China National Standard (GB 15618-2018). The results of BCR sequential extraction procedure showed that the biochar amendment promoted the transformation of Cr from the acid soluble and reducible fractions to the oxidizable and residua fractions, reducing Cr bioavailability in the soil. Meanwhile, biochar amendment effectively reduced the leaching ability of Cr. In addition, biochar amendment increased soil pH, CEC, organic matter, and available phosphorus in the soil, which were conducive to the immobilization of Cr. The possible immobilization mechanisms includes ion exchange, precipitation/co-precipitation, complexation, but the influence of the biochar on the valence of Cr in soil needs further study.
