- Abstract:
-
Natural resourees of halloysite nanolubes and chitosan were used to prepare CiS/HNT hybrid por.ous beads with reversed-phase cross-linking and freeze drying technique, using glutaradehyde as a cross-linkerand ’Tween80 as the emulsifier. The hybrid beads were charaeterized by seanning eleetron microseope(SEM). The SEM image shows that hybrid bead is a porous structure comprised of chitosan and aceumulatedhalloysite nanolubes. The CTS/HN’T porous beads were used as adsorbent to remove anionie dye of methyl or.ange ( MO ) from aqueous solution. The elfeet of pH , MO initial eoneentration and eontaet time were investigated. The adsorbent exhibited good stability, relatively high adsorplion eapacity and eould maintain high remov.al efficieney of above 88% afer 10 times of cyclie utilization.
