| 内容記述 | To remove toxic chromium ions from aqueous solution, pendant amino/amido ligand adsorbents onto a fine polyethylene fabric with a nonwoven form were synthesized by electron beam induced graft polymerization of 4-Chloromethylstylene/acrylonitrile monomer and subsequent chemical modification. The ligand density of the obtained grafted adsorbents ranged from 3.6 to 4.2 mmol/g- adsorbent. In batch adsorption tests, the amine- and amide-type adsorbents were performed in trivalent chromium (Cr(III)) and hexavalent chromium (Cr(VI)) solution having a concentration of 100 ppb in the pH range from 2 to 7. As a result, the resultant amine-type adsorbent had higher affinity for Cr(IV) at pH 3-5, and amido-type’s had for Cr(III) at pH 5-7. Almost all adsorbed Cr on the grafted adsorbent could be eluted in acidic solution, and the adsorbent can be used repeatedly after the elution of Cr. Column mode adsorption tests indicated that the adsorption rate of the obtained fibrous adsorbents had much higher than that of general granular shaped resin. | |||||
