Carbonaceous materials for removal and recovery of phosphate species: Limitations, successes and future improvement

Towards engineering mitigation of leaching of Cd and Pb in co-contaminated soils using metal oxide-based aerogel composites and biochar

“…A wide range of CAg samples with various porous structures, i.e., micro-, meso-and micro-porous, are synthesized to be embedded into metal oxides. 41,68 The CAg, consisting of resorcinol-formaldehyde (RF) polymer chains, contains plentiful oxygen-containing functional groups. Modication of metal oxides with CAg allows binding among functional groups in the CAg polymer chains and therefore prevents the aggregation of metal oxides during synthesis or when metal immobilization/stabilization occurs in the treated medium.…”

Feasibility of electrodeionization for phosphate removal

“…Phosphate can be eliminated from water samples by various techniques, including adsorption, biosorption, biological processes, ion exchange, chemical precipitation, coagulation/flotation, and membrane processes. Numerous researchers in the past years have reviewed the advantages, limitations, and applications of some of these methods (Almanassra et al, 2021; Huang et al, 2017; Liu et al, 2022; Recepoglu et al, 2022; van Loosdrecht et al, 1997; Zheng et al, 2022).…”

Synthesis of MgAl-LDH@ZIF-8 composites by in situ growth method for highly efficient phosphate removal

“…1 Among them, China has discharged more than 300 000 tons of phosphate-containing wastewater. 2 Phosphate in sewage mainly comes from phosphate mining, agricultural and industrial activities, and urban sewage. Studies have shown that phosphate concentrations in untreated wastewater usually range from 5 mg L −1 to 30 mg L −1 .…”
