Crosslinked chitin was prepared from epichlorohydrin and chitin which was isolated from waste marin source. The crosslinked chitosan were prepared by the deacetylation of the crosslinked chitin with a strong base. 2,2'-Iminodibenzoic acid-crosslinked chitosan was prepared by reacting 2,2'-Iminodibenzoic acid salt with crosslinked chitosan-Cl which was obtained by chlorination of crosslinked chitosan. The adsorptivity of Pb(II), Cu(II), Cd(II) was studied as a synthetic adsorbent. Experimental results for the adsorption and the recovery characteristics showed that the more pH increase, the more amount of adsorbed metal ion increase. Optimum adsorption time was 1 hr, and adsorption capacity was increased in order of <TEX>$Cu^{2+}$</TEX><<TEX>$Cd^{2+}$</TEX><<TEX>$Pb^{2+}$</TEX>, and recovery capacity was increased in order of <TEX>$Cd^{2+}$</TEX><<TEX>$Cu^{2+}$</TEX><<TEX>$Pb^{2+}$</TEX>.
