Abstract：The removal of Cr6+ from water using nanoscale zero-valent iron (nZVI) prepared with the liquid phase reduction method was investigated. Results showed that removal rate of Cr6+ observed from nZVI was much higher than those from iron powder and activated carbon. Lower pH and initial Cr6+ concentration, more fresh nZVI and dosage were favorable of removal of Cr6+ in water, and the best removal rate was nearly 100%. The fitting results of reaction dynamics indicated that Cr6+ removal by nZVI was well consonant with pseudo second-order model. Cr element with 12.02% (wt) concentration was detected on the post-reaction nZVI particle surface by SEM and EDS. The analysis of Cr6+ and Cr3+ concentration in reaction solution of adsorption, suggested that reduction and co-precipitation should be the mainl mechanism of the Cr6+ removal from water using nZVI.
