Phosphate removal and recovery by lanthanum-based adsorbents: A review for current advances

Sludge-based biochar with lanthanum modification for phosphate recovery from wastewater streams

“…With the low risk of the leached metal under various solution conditions, the phosphate-loaded SBP-La is promising to be used as a phosphate fertilizer for agricultural applications. 35 Meanwhile, the phosphate from exhausted SBP-La can be extracted and further treated for production of phosphorus containing products. 8…”

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

“…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. 37 In the last few years, various La-based composites like lanthanum hydroxide anchored granular activated carbon, La-impregnated alumina, Mg-Fe-La composites, La@ABDC, La-BDC, HAp-La-BTC-MOFs, and Hap-La-BTC MOFs@Alg-CS hybrid beads have been reported for defluoridation as they provide reactive sites for ligand exchange or complexation with fluoride ions. [38][39][40][41][42][43][44] Herein, the defluoridation study emphasises the use of a green microwave-assisted technique for the synthesis of La@ATPA and La@TPA.…”

Phosphate removal by ex situ generated Fe (hydr)oxides from scrap iron electrocoagulation: the critical role of coprecipitation

“…[6][7][8] In the China and United states, the discharge of phosphate is both limited to 0.5-1.0 mg/L. 5 To meet the strict discharge requirements on P content, technologies including chemical precipitation, 9,10 adsorption, [11][12][13] and enhanced biological P removal 14 have been developed. Among the methods, adsorption by a suite of Fe (hydr)oxides (e.g., ferrihydrite, magnetite, and goethite) has shown promise for phosphate removal owing to the advantages of environmental friend, low cost, and easy regeneration.…”
