Research Progress in Removal of Arsenic by Iron-based Adsorbents and Their Modified Products
Arsenic pollution in water is a serious worldwide problem.Therefore,developing suitable adsorbents has become an important task for environmental researchers.As a common adsorbent material,iron-based adsorbents have caused extensive concern for their efficient adsorption of arsenic.In this paper,the characteristics and As removal mechanisms of iron-based adsorbents and their modified products are summarized.Finally,the prospects of the future research direction of iron-based adsorbents were forward.
