    Abstract

    A porous hollow-fiber membrane containing an iminodiethanol (IDE) group as the chelate-forming group was applied to the recovery of antimony in the permeation mode. An antimony solution was forced to permeate through the pores of the chelating porous hollow-fiber membrane, driven by a transmembrane pressure. The membrane with a thickness of 0.7mm and a porosity of 70% had an iminodiethanol group of 1.6mol/kg of the membrane and a water flux of 0.95m/h at 0.1MPa and 298K. The breakthrough curves of antimony overlapped irrespective of the permeation rate of the antimony solution ranging from 2 to 20ml/min, i.e. the residence time across the membrane thickness ranging from 3.4 to 0.34s, because of negligible diffusional mass-transfer resistance of the ionic species of antimony to the iminodiethanol group. At antimony concentrations below 10mg/l (pH 4.0), a linear adsorption isotherm was obtained. The adsorbed antimony was quantitatively eluted by permeation of 2M hydrochloric acid through the pores of the membrane.
