Phosphate adsorption improvement using a novel adsorbent by CaFe/LDH supported onto CO activated biochar.

It is imperative to remove phosphate from the aquatic system. This nutrient in excess can cause environmental problems such as eutrophication. Therefore, aiming to enhance phosphate removal, this work presents a novel adsorbent developed from the construction of Ca/Fe layer double hydroxides (CaFe/LDH) supported onto biochar physically activated with CO [CaFe/biochar (CO)].
