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: Herein, a ternary mechanism for U(VI) uptake in metal–organic frameworks was reported.Specifically, hydrated uranyl ions form outer-sphere complexes in the surface of MIL-100s (Al, Fe) byexchanging with hydrogen ions of terminal hydroxyl groups (Al-OH2, Fe-OH2), and/or, hydrated uranyl ions are bound directly to Al(III) center in MIL-100(Al) through a strong inner-sphereThe present study suggests that changing metal center of metal–organic frameworks and sorption conditions

Effects of metal ions on the morphology of calcium sulfate hemihydrate whiskers by hydrothermal method

Tianjie Liu, Hao Fan, Yanxia Xu, Xingfu Song, Jianguo Yu

Frontiers of Chemical Science and Engineering 2017, Volume 11, Issue 4,   Pages 545-553 doi: 10.1007/s11705-017-1665-8

Abstract: The effects of Na , Mg , Al and Fe ion concentrations on the crystal morphology of calcium sulfate hemihydrate whiskers formed via a hydrothermal method have been studied. In the presence of Al concentrations higher than 1×10 mol/L the whiskers were significantly shorter and thicker and the presence of Mg and Fe resulted in shorter whiskers. The presence of Na did not affect the morphology of the whiskers. Through elemental analysis, it was determined that Mg and Al were selectively adsorbed on the surfaces of the crystals, whereas Fe underwent a hydrolysis reaction to form a brown precipitate which decreased the ion concentration in the solution. These results indicate that in raw materials used for the industrial preparation of calcium sulfate whiskers, Al and Fe should be removed and the Mg concentration should be less than 8 × 10 mol/L in order to obtain pure whiskers with high aspect ratios.

Removal of Cu(II) ions from aqueous solution by activated carbon impregnated with humic acid

LIU Hanchao,FENG Suping,ZHANG Nannan,DU Xiaolin,LIU Yongli

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 3,   Pages 329-336 doi: 10.1007/s11783-013-0553-9

Abstract: Humic acid (HA) was impregnated onto powdered activated carbon to improve its Cu(II) adsorption capability. The optimum pH value for Cu(II) removal was 6. The maximum adsorption capacity of HA-impregnated activated carbon was up to 5.98 mg·g , which is five times the capacity of virgin activated carbon. The adsorption processes were rapid and accompanied by changes in pH. In using a linear method, it was determined that the equilibrium experimental data were better represented by the Langmuir isotherm than by the Freundlich isotherm. Surface charges and surface functional groups were studied through zeta potential and FTIR measurements to explain the mechanism behind the humic-acid modification that enhanced the Cu(II) adsorption capacity of activated carbon.
