Needle-like Mg-La bimetal oxide nanocomposites derived from periclase and lanthanum for cost-effective phosphate and fluoride removal: Characterization, performance and mechanism

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.…”

Efficient recovery of phosphate from simulated urine by Mg/Fe bimetallic oxide modified biochar as a potential resource

“…The spectrum of O 1s (Fig. 6e) showed that before the adsorption reaction, the peak of O 1s in the Mg/Fe biochar could be decomposed into the peaks with binding energy of 529.8, 531.0 and 532.1 eV, which were attributed to M-O (M = Mg or Fe), -OH, and bound H 2 O (Kong et al, 2020). After the adsorption reaction, the ratio of M-O bond decreased from 35.2% to 26.5%, while the ratio of -OH increased from 26.9% to 35.7%.…”

Ultra-fast and robust capture of fluoride by an amino terephthalic acid-facilitated lanthanum-based organic framework: insight into performance and mechanisms

“…Lanthanum (La) is a low-cost rare-earth metal that is both environmentally benign and biocompatible. 35 La has been reported to be remarkably successful for fluoride sorption due to its high electron affinity when compared to other rare earth metals. 36 Due to their strong affinity, excellent selectivity, wide pH range and outstanding metal stability, lanthanum (La)-based sorbents can be considered as suitable materials for fluoride removal.…”
