抄録	A kinetic study of lead adsorption to composite biopolymer adsorbents was carried out. Spherical and membranous adsorbents containing two kinds of biopolymers, humic acid and alginic acid, were used for lead adsorption in dilute acidic solutions. The shrinking core model derived by Rao and Gupta was applied to describe the rate process of lead adsorption to spherical adsorbents (average radii of 0.12, 0.15, and 0.16 cm). Furthermore, the shrinking core model was modified and adapted for the description of the rate process of lead adsorption to membranous adsorbent (an average thickness of 0.0216 cm). The adsorption rate process for the both cases was well-described and the average apparent lead diffusion coefficients of about 6 × 10-6 and 7 × 10-6 cm2・s-1 were found for the spherical and membranous adsorbents, respectively.
