A novel adsorbent embedding Mg-Al-Zr mixed oxides with millimetre-sized calcium alginate beads (SA-CMAZ) was synthesized, characterized, and applied for the secondary removal of fluoride from wastewater. Key factors affecting the fluoride adsorption, including initial fluoride concentration, contact time, initial pH and coexisting anions, were investigated. The results showed that fluoride could be removed by SA-CMAZ over a wide pH range, from 4 to 10. The presence of coexisting anions weakened the adsorption of fluoride, and the decreasing order of the removal towards fluoride was PO43−...
