摘要
A physicochemical method was used to adsorb glycerin in saline wastewater by strong base anion resin(D201).Boric acid,a kind of weak acid,can combine with glycerin,and a specific complex can be produced,which possess bigger molecule than glycerin.Then,this specific complex could be adsorbed by strong base anion resin.Via the experiment,the equation of adsorption isotherm with D201 at 20℃ can be shown by lgx/m=1.74lgCe–5.72;for column test with simulative glycerin wastewater,the treatment capability was more than nine bed volumes,and 39.77 mg glycerin could be removed by per gram resin.When the NaCl concentration was 10 g/L,five bed volumes of simulative wastewater could be treated,and the adsorb mass was 29.09 mg/g.When the NaCl concentration was 30 g/L,only three bed volumes of simulative wastewater could be treated,and the adsorb mass was 14.83 mg/g.
