The following dry composite beads (diameter 1.0‐1‐2 mm) were prepared: chitin‐CaCO 3 , chitosan‐CaCl 2 . chitosan‐CuCl 2 , partially N‐acetylated chitosan‐CuCl 2 , chitosan‐CuSO 4 , chitosan‐Fe 3 O 4 , chitin‐SiO 2 . Each of chitosan‐CuCl 2 , chitosan‐CuSO 4 and chitin‐CaCl 2 composite beads was treated in aqueous K 2 CO 3 at room temperature to afford a mixture of metal carbonates and hydroxides on chitin or chitosan chain.
