Cr(VI) is a known toxic heavy metal which is found frequently in many industrial sites. Contaminates soil and ground water with Cr(VI) is a big enviromental concern due to the high toxicity. Permeable Reactive Barrier(PRB)is an innovative remedial technology intensively studied and developed recenty. The most popular PRB material is zero-valent iron which is environmentally favorable and cheap. Scrapped steels and precleaned scrapped steels were tested in this study for Cr(VI). Scrapped steels were precleaned wuth detergent, acetone, hexane.The precleaned scrapped steel showed relatively high reactivity for Cr(VI). The results indicate that the scrapped steel could be used as PRB material after proper pretreatments.
