Abstract :
Crosslinked chitosan ( CCTS) was prepared with crude macromolecule compound chitosan as a matrix material and epichlorohydrin as crosslinked reagent under alkaline conditions. The adsorption behavior of nitrite from water by CCTS was studied. Then the effects of the CCTS amount, adsorption time, pH, temperature, initial nitrite concentration, on its adsorption performance were discussed. The optimum experimental condition was determined, under which the maximum removal rate can reach 92.5%. Finally, the adsorption mechanisms were summarized.
