Chitosan–cellulose gel beads were regenerated from an ionic liquid, and their application to a metal adsorbent was examined. The chitosan–cellulose gel beads, which were prepared from 1-ethyl-3-methyl imidazolium acetate, were more stable in the acidic and basic aqueous solutions than cellulose or chitosan. The adsorption of copper on chitosan–cellulose gel beads was examined, and the adsorption amount of copper ion increased with pH, suggesting that amino groups on chitosan were related to adsorption. The adsorption isotherm of copper, zinc, and nickel ions was well described by the Langmuir model, and the adsorption ability of these metal ions obeyed the Irving-Williams series. Fe3+, Mn2+, and Co2+ from a buffer solution and Pt4+, Au3+, and Pd2+ from a hydrochloric acid solution were not adsorbed on the chitosan–cellulose gel beads.
