Different types of adsorbents for selenium (Se) removal from water: A review

Abstract

Development of adsorption materials based on metal oxides, silicon dioxide, carbon, biosorbents and adsorbents, obtained from natural waste, can be used to remove selenium from water. Research on some of these materials is at the laboratory level, while the others were tested in the pilot plants, and a few have found a commercial application. The high adsorption capacities show a possibility of their application for selenium removal from water. This paper presents a literature review of different types of adsorbents for the removal of selenium (Se) from water.
