Abstract
In this work, hydro ceramsite (HC) was coated by layered aluminum oxyhydroxide (LAO) with the assistance of Iron(III)-alginate (IA) to obtain HC@LAO-IA. Iron(III)-alginate (IA) and layered aluminum oxyhydroxide (LAO) assist in the improvement of the adsorption capacity of hydro ceramsite (HC) for Se(IV), Se(VI), and As(V) via hydrogen bonding, electrostatic adsorption, and inner sphere complexation, respectively. HC@LAO-IA showed superior removal of Se(IV), Se(VI), and As(V) under simulated and actual environmental conditions in the presence of multiple competing anions (Cl-, NO3-, CO32-, PO43- and SO42-), particularly excelling in high-concentration sulfate wastewater, and also has a wide pH application range of 3-10. After four reuse cycles, HC@LAO-IA still exhibits satisfactory performance. Sand column experiments also demonstrated that HC@LAO-IA has excellent capabilities for the removal of Se(IV), Se(VI), and As(V) from real wastewater obtained from a metallurgical process plant. This work provides a promising, low-cost approach to remove Se and As from aqueous solutions and a new route for ceramsite recycling.
