La-based-adsorbents for efficient biological phosphorus treatment of wastewater: Synergistically strengthen of chemical and biological removal

Phosphate substances transformation and vivianite formation in P-Fe containing sludge during the transition process of aerobic and anaerobic conditions

“…It has the advantages of flexible process, strong controllability, avoiding the use of chemicals, avoiding secondary pollution, which can be easy to realize automation and high energy efficiency ( Nguyen et al, 2016 , Omwene et al, 2018 ). The biological method reduces phosphate content in wastewater by transferring phosphate to sludge phase ( Liu et al, 2020 ). The above methods of phosphorus removal will produce large amounts of phosphorus-rich sludge that require additional treatment.…”

Microwave- and ultrasonic-assisted synthesis of 2D La-based MOF nanosheets by coordinative unsaturation degree to boost phosphate adsorption

“…Similar to in the literature, the change in ionic strength does not affect adsorption. 35,40,41 Based on this, the prepared 2D Ln-TDA (Ln = La, Ce) nanosheets (Ln = La, Ce) can be used in real wastewater treatment.…”

“…This result indicated that the structure of the designed nanosheets, which had a tight structure, was not changed after phosphate adsorption. 19,34,35,41…”

Nanostructured LaFeO3/Si thin films grown by pulsed laser deposition

“…Evidently, it is not a clear-cut statement since A-site deficiencies or stoichiometry modification can result in modulations of B-site ions' valence and oxygen vacancies and, as a result, influences the catalytic process [8,9]. The choice of lanthanum in A-site cation, other than its environmental-friendly and biocompatibility characteristics [10], is explained by its slightly larger ionic radius as compared to most of the (3+) rare earth cations. It is believed that this large ionic radius will have for consequence to lower the B-O bond strength and, in return, helps the catalytic process [11].…”
