Alkali lignin, Modification, Quaternary ammonium salt, Cr(Ⅵ), Anion adsorbent Abstract. LIA(lignin ionic adsorbent) was synthesized by modified alkali lignin after reaction with epichlorohydrin and dimethylamine or diethylamine by using the modifying agents of N-methylmorpholine (NMM) in the presence of organic medium of N,N-dimethylformamide(DMF). The LIA was characterized by FTIR spectroscopy and elements analysis, the yield of products and the adsorbent capabilities for Cr(Ⅵ) from aqueous solution were also exploited. The factors that might influent the adsorption performance were investigated, such as adsorption time, reagent dosage and the initial concentration of Cr(Ⅵ). It was found that the efficiency of Cr(Ⅵ) removal were better when the amount of the sorbent was increased. But the removal efficiency was reduced as the initial concentration of Cr(Ⅵ) increased. The contrast result of the two synthesis processes also proved the yields of sample 3 (modified alkali lignin using diethylamine) was higher than sample 2 (modified alkali lignin using dimethylamine). And the adsorption capabilities of sample 3 were also better than sample 2.
