Abstract

Abstract

To reveal the key factors that limit the remediation effectiveness of heavily chromium contaminated soil,the desorption kinetics,and insoluble Cr (Ⅵ) reduction experiments were carried out in this study.The results showed that leaching with citric acid could significantly reduce the concentration of insoluble Cr (Ⅵ) in soil samples at room temperature,and increasing the leaching temperature to 90℃ could further decrease the concentration of insoluble Cr (Ⅵ).The lower the concentration of insoluble Cr (Ⅵ) in the soil after leaching,the better the remediation effectiveness.For the soil samples used in this study,the concentration of Cr (Ⅵ) decreased from (1813.2±59.8) mg/kg to (99.1±8.8) mg/kg by high-temperature flushing with citric acid and high-temperature reduction with ferrous sulfate.In addition,the reduction of insoluble Cr (Ⅵ) by citric acid in the leaching experiment could be ignored and the residual citric acid in the soil sample had no significant effect on the detection results of Cr (Ⅵ) in soil.This study proved that the reduction effectiveness of insoluble Cr (Ⅵ) was the key limiting factor for the remediation of heavy chromium-contaminated soil,and provided a reference for the research and development of remediation technology for chromium contaminated soil.
