Abstract


In this study, iron nanomaterial was synthesized by a reaction between FeCl3 and NaBH4 using microfluidic device as a microreactor which is prepared by photolithography and soft molding processes. Morphology and structure of the as-prepared nanomaterial was characterized by scanning microscope and X-ray diffraction analysis methods. The collected product is zero valent iron material with the morphology is nano-sheet with the thickness is approximatly 50 nm. Hexavalent chromium ion from K2Cr2O7 solution could be removed by the as-prepared iron nanomaterial. The removal of ions Cr(VI) is determined and confirmed by the visible ultraviolet (UV-Vis) absorption spectroscopy which is proportional to the amount of nanomaterial used and is influenced by pH conditions.
