“…The choice of these two ions was closely aligned with our primary objective: to use a natural, or develop a modified, sorbent to apply directly in agriculture practices. This application needed to be achieved without introducing additional substances, and in every case without leaving residues from the modifying treatment that could pollute the soil or cause undesirable effects on plant growth (an example being the use of zirconium as a bridge between natural biomass and phosphate [ 6 ]). The Ca-enriched biomass, in contact with H 2 PO 4 − fails to establish chemical-physical interaction, which is what happens between Ca and HPO 4 2− ions.…”

“…These approaches aim to maximize the utility of waste materials while ensuring sustainable P management [ 5 ]. Numerous studies have explored the capacity of various biomass adsorbents, including corn bracts [ 6 , 7 ], sugar cane bagasse [ 8 ] and wheat straw [ 9 ], dried cactus pear pruning [ 10 , 11 ]. Currently, cactus pear thrives in semi-arid regions across the globe and finds significant cultivation in the Mediterranean basin and Central America.…”

“…Phosphate adsorption usually reaches an optimal level when the pH promotes its electrostatic attraction to the adsorbent, i.e., when the pH of the solution is lower than that of the zero-charge point (ZPC) of the adsorbent, making it electropositive. Since several adsorbents have a ZPC near-neutral pH, optimal P adsorption is often in the acidic range [73][74][75][76][77][78][79].…”

Many intensively farmed soils show high phosphorus (P) contents compared to the thresholds required for agricultural production; 0.084 Mt of P year−1 is leaving the European terrestrial system. This paper focuses mainly on non-point flows of P and provides an overview of the most promising and sustainable solutions for P recycling, centred on waste materials from agriculture. Given the global shortage of the primary resource of P, its management is critical for its efficient use. Nowadays, wastage and loss at every stage of the P cycle raise concerns about future supplies and especially about the resulting environmental problems, such as the eutrophication of surface water bodies and the reduction of biodiversity. Recovering P costs more than EUR 640 per tonne depending on the type of technique used. The opportunity for P recovery with green and sustainable technology is, therefore, a great challenge for the next years. Waste materials or by-products of agricultural processing have been considered ecologically safe, low-cost, and highly selective with high pollutant adsorption capacities, which would enable sustainable P recovery, both environmentally and economically. A realistic threshold for considering the reuse of P sustainably at the farm level is EUR 320 per tonne.

“…Several methods to remove phosphate from water have been investigated in recent decades. The methods mainly include biological, phytoremediation, precipitation, and adsorption. , Among them, adsorption presents a low cost associated with high flexibility, design simplicity, and selectivity, making it ideal for sustainable phosphorus removal from effluents. ,, Unlike other techniques, it is also an excellent treatment for water contaminated with low phosphate levels since environmentally relevant phosphate concentrations range from trace levels to a few milligrams per liter. Bacelo et al reviewed many materials such as metal oxides/hydroxides, carbonate minerals, clay minerals, zeolites, porous silica, activated carbon, biochar, polymers, bioderived materials, and industrial waste that have been used in the adsorption of phosphate.…”

To prevent eutrophication, controlling the phosphate concentration levels is one of the most important issues in surface water management. One of the most utilized methods is phosphate adsorption. However, its application faces a bottleneck due to the unclear understanding of adsorption and interaction mechanisms. The present work unlocks the phosphorus adsorption mechanisms in three-dimensional reduced graphene oxide with different reduction levels and pore sizes to remove phosphate from water using experiments and multiscale simulations. Experiments were performed to evaluate the influence of pH, ionic strength, and temperature on the adsorption. Molecular Dynamics and Ab Initio simulations evaluated the influence of the pore size and oxidation degrees of the materials. We show that the adsorption capacity of the materials increases with increasing pH and ionic strength and decreasing temperature. It is observed that the more oxidized the material and the less compact the structure, the better the adsorption. These results are theoretically explained in terms of the interaction of functional groups and the clustering of phosphate ions, which results in better adsorption in materials with larger pores. The underlying mechanisms for the 3D-reduced graphene oxide performance were confirmed by spectroscopy analysis. All the results show that 3D-reduced graphene oxide can sorb phosphate in different complex water remediation systems with characteristics that can be modulated by changing the material synthesis method.
