Summary:In this work, the efficiency of date palm wastes derived biochar functionalized with Mg/Al layered double hydroxides (LDH) in removing phosphorus (P) from aqueous solutions was investigated under static and dynamic conditions. The deep characterization of the functionalized biochar showed that compared to raw biochar, its physico-chemical properties have been significantly improved. This improvement has resulted in a significant enhancement of P recovery from aqueous solutions under a wide experimental conditions of contact time, pH, doses, etc. The maximum adsorption capacity of P was estimated to be about 14.1 and more than 9.0 mg/g in batch and laboratory column modes. These P-loaded-modified biochars can be valorized as eco-friendly amendment for agricultural soils which promotes sustainability and circular economy concepts in the management of both liquid and solid wastes.
