Abstract: Hexavalent chromium is a soluble, mobile, and highly toxic metal ion in groundwater. Adsorption by permeable reactive barriers (PRBs) with special sorbent is a common method to remove hexavalent chromium. A series of experiments have been performed to remove hexavalent chromium in groundwater under PRB with modified chitosan. Therefore, in this paper, the authors first estimated adsorption characteristics of the modified chitosan in a column test, and then calibrated the PRB adsorption parameters in a sandbox test, and finally designed an optimal width, length, and depth of the PRB with the same reactive media in a three-dimensional aquifer. The results showed that the modified chitosan might be a potential adsorption medium. The design schemes can meet the water quality standard of 0.1 mg/L Cr(VI). Heterogeneity of dispersion is a crucial factor when designing the PRB. Therefore, the design of the PRB structures can be appropriate and serve as reference for groundwater remediation
