Fluoride ions adsorption from water by CaCO enhanced Mn–Fe mixed metal oxides

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 2,   Pages 236-248 doi: 10.1007/s11705-022-2193-8

Abstract: The adsorption property of CMFC toward fluoride ion was analyzed by batch experiments.In fact, CMFC exhibited adsorption capacity of 227.3 mg∙g‒1 toward fluoride ion.Results showed that ion exchange, electrostatic attraction and chemical adsorption were the main mechanismfor the adhesion of large amount of fluoride ion on the CMFC surface, and the high adsorption capacityresponded to the low pH of the adsorption system.

A ternary mechanism for the facilitated transfer of metal ions onto metal–organic frameworks: implications

Frontiers of Chemical Science and Engineering   Pages 1632-1642 doi: 10.1007/s11705-022-2187-6

Abstract: It depends on a comprehensive knowledge of a “real sorption mechanism”.Herein, a ternary mechanism for U(VI) uptake in metal–organic frameworks was reported.Besides, the sorption mechanism is also pH and ionic strength dependent.suggests that changing metal center of metal–organic frameworks and sorption conditions alters sorption mechanism
