6-(Alkylamino) deoxycelluloses were prepared from 6-chlorodeoxycellulose and n-alkylamines, CH₃ (CH₂)_mNH₂ (m=5, 11, 17), and their adsorption behavior of divalent heavy metal ions, Co²⁺, Ni²⁺, Cu²⁺ and Cd²⁺, was examined.<br>Metal ions were adsorbed on these alkylaminocelluloses in weakly acidic solution. The proportion of adsorbed metal ions increased with increasing pH of the solution and was dependent on the length of the alkyl chain in the order of n-stearylaminodeoxycellulose (m=17)> n-laurylaminodeoxycellulose (m=11)>n-hexylaminodeoxycellulose (m=5). The adsorptive activity of n-laurylaminodeoxycellulose was found to be in the order of Cu²⁺>Co²⁺, Cd²⁺>Ni²⁺. Since these adsorbents had a single coordination site in the pendant groups, the proportion of adsorption against metal ions was much lower than that of cellulose derivatives having two coordination sites in the pendant groups reported previously.
