In comparison with untreated glutaraldehyde crosslinked chitosan resin beads, the hydrogen reduced ones showed a quite realistic behavior in the adsorption upon those model toxins, and the amount of adsorption was fairly high while the equilibrium time was obviously shortened.展开更多
文摘Glutaraldehyde crosslinked chitosan used in the adsorption upon model uremic middle molecular toxins was studied. In comparison with untreated glutaraldehyde crosslinked chitosan resin beads, the hydrogen reduced ones showed a quite realistic behavior in the adsorption upon those model toxins, and the amount of adsorption was fairly high while the equilibrium time was obviously shortened.
