The use of permeable reactive barriers (PRB) has been drawing the attention of researchers for groundwater contaminations. Searching for a new material capable to reduce hexavalent chromium, this work proposes the application of a steel waste (BFD) as reactive media to reduce and precipitate chromium in loco. Batch tests wore developed in order to check the applicability of the residue on the reduction process. Results of batch tests showed that BFD can reduce up to 60% of hexavalent chromium on solution.
