Hexavalent Chromium Immobilization in Soil by Sludge Biochar Tubules Under Fluctuating Groundwater: Performance, Mechanisms and Engineering Potential

Although biochar has been widely applied for chromium (Cr)-contaminated soil remediation, its direct mixing with soil is limited by poor recoverability and insufficient long-term stability, while the role of groundwater table fluctuation (GTF) is often overlooked. In this study, we developed a biochar tubule-based stra...
