副生酸化鉄のヒ素吸着剤としての利用検討

In this study, we examined the utilization of regenerated amorphous iron oxide for adsorbent of arsenic in underground water in order to develop the low-priced- and simplifiedarsenic treatment method. It was found the this iron oxide could remove arsenic in low concentration regardless of its valence state for a long time, and also with high selectivity under coexistence of anions. These results indicate that iron oxide is available for the treatment of arsenic in various water, in particular, in the Southeast Asia that requests a small and maintenance-free equipment.
