	1	Adsorption of glycine at the anatase TiO_(2)/water interface: Effects of Ca^(2+) ions显示文摘Adsorption reactions of amino acids(AAs)on TiO_(2) nanoparticles(NPs)play an important role in the available nutrients in soils and sediments.The pH effects on glycine adsorption have been studied,but little is known about its coadsorption with Ca^(2+)at the molecular level.Combined attenuated total reflectance Fourier transform infrared(ATR-FTIR)flow-cell measurements and density functional theory(DFT)calculationswere used to determine the surface complex and corresponding dynamic adsorption/desorption processes.The structures of glycine adsorbed onto TiO_(2) were closely associated with its dissolved species in the solution phase.The presence of Ca^(2+)exerted different influences on glycine adsorption within pH 4−11,thus affecting its migration rate in soils and sediments.The mononuclear bidentate complex at pH 4−7,involving the COO−moiety of zwitterionic glycine,remained unchanged in the absence and presence of Ca^(2+).At pH 11,the mononuclear bidentate complex with deprotonated NH2 can be removed from the TiO_(2) surface upon coadsorption with Ca^(2+).The bonding strength of glycine on TiO_(2) was much weaker than that of the Ca-bridged ternary surface complexation.Glycine adsorption was inhibited at pH 4 but was enhanced at pH 7 and 11.
