研究開始時の研究の概要 |
The motivation of this research is the development of advanced metal oxide materials and their composites for hazardous hexavalent chromium (Cr (VI)) mitigation. The removal of Cr(VI) ions from contaminated water can be achieved by either adsorption or photoreduction process. The development of this study would be beneficial for wastewater treatment technology toward sustainability.
