Abstract
This paper aims at synthesize titanium dioxide loaded with nano-zero valent iron (nZVI-TiO2) from an inexpensive ilmenite ore. Ilmenite leachant, a solution rich in both titanium and iron ions,has been prepared by leaching ilmenite ore in hydrochloric acid. At 30% HCl, 70 ○C and 5 hours, almost all of iron and titanium in the ilmenite ore were dissolved. Nano titania was then produced by hydrolysis of the ilmenite leachantin boiling water under open atmosphere and nano-zero valent iron (nZVI) was subsequently precipitated on its surface by reduction with sodium borohydride. The synthesized nZVI-TO2was characterized by TEM, UV-Vis absorption, XRD and EDXRF and tested for reduction of nitrate from water. The synthesized material showed a good performance in reduction of nitrate in water compared with nZVI.About 40% of nitrate could be removed using nZVI-TO2 from nearly neutral pH water after 3 hours.
