Low-Cost Efficient Magnetic Adsorbent for Phosphorus Removal from Water.

ABSTRACT: Adsorption using magnetic adsorbents makes the phosphorus removal from water simple and efficient. However, most of the reported magnetic adsorbents use chemically synthesized nanoparticles as magnetic cores, which are expensive and environmentally unfriendly. Replacing the nanomagnetic cores by cheap and green magnetic materials is essential for the wide application of this technique. In this paper, coal-fly-ash magnetic spheres (MSs) were processed to produce a cheap and eco-friendly magnetic core. A magnetic adsorbent, ZrO₂ coated ball-milled MS (BMS@ZrO₂), was prepared through a simple chemical precipitation method. Careful structural investigations indicate that a multipore structural amorphous ZrO₂ layer has grown on the MS core. The specific surface
