Abstract

In order to solve the problem of the separation of defluorinated adsorbents and the loss of effective components,SA@LHMS adsorbents were prepared with sodium alginate(SA) and lanthanum hydroxide modified Y zeolite (LHMS) as raw materials.The optimum preparation conditions of adsorbent were determined by orthogonal experiment.The effect of factors,such as dosage of adsorbent,pH and co-existing ions etc.,was tested by batch adsorption experiment,and the adsorption performance of adsorption rate and adsorption isotherm was researched.The results showed that the adsorption rate curve of the SA@LHMS conformed to the second-order reaction rate equation.Adsorption isotherm conformed to the type Ⅱ isotherm,multilayer physical adsorption.The initial pH (3~12) had no significant effect on the adsorption effect.High concentration of co-existing anions (50 mg/L) inhibited the adsorption process.The regeneration effect of 1 mol/L and 2 mol/L NaOH solution on SA@LHMS was better,and SA@LHMS still retained a high adsorption capacity after three regeneration.The surface and cross section morphology of SA @LHMS as well as the surface morphology before and after adsorption were significantly different.EDS component analysis and FT-IR spectrum analysis before and after adsorption showed that ligand exchange occur-curred between F- and —OH on the surface and inside of particles during adsorption.
