@@@@Highlights •Chitosan bentonite compounds (CSBT) had a good passivation effect on soil chromium.•CSBT can convert effective chromium into residual chromium.•CSBT had no effect on soil pH.•The surface functional groups amino, carboxyl and hydroxyl iron participate in the passivation of soil chromium.
