| 摘 要： | Bispyribac-sodium is a weakly acidic herbicide with high water solubility and is thus a potential source of groundwater contamination. Considering the risk inherent to the use of this herbicide, this study assessed the impacts of rice straw(RS) and biochar amendments on the adsorption and leaching behavior of bispyribac-sodium in soil. Biochars were produced from RS at different pyrolysis temperatures and characterized using various spectral techniques.Rice straw had a surface area of 3.996×10
