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

A sorbent consisting of a lanthanum-loaded metal–organic framework, involving terephthalic acid (La@TPA) and amino terephthalic acid (La@ATPA) as organic linkers, was synthesized and evaluated for fluoride (F) removal from groundwater.
