In this study, we examined the conditions of manufacturing material for the purpose of getting one which has more amorphous structure and lager surface area to develop the technology which makes use of regenerated amorphous iron oxide for the low-priced- and simplified-method of treating arsenic in underground water. It was found the changing a condition of neutralizing iron sulfate of raw material prevented the growth of crystal, and produced a material which has large surface area. These results indicate that the application with this material realizes a design of durable and compact water purifier.
