| Abstract: | The following dry composite beads (diameter 1.0-1-2 mm) were prepared: chitin-CaCO3, chitosan-CaCl2. chitosan-CuCl2, partially N-acetylated chitosan-CuCl2, chitosan-CuSO4, chitosan-Fe3O4, chitin-SiO2. Each of chitosan-CuCl2, chitosan-CuSO4 and chitin-CaCl2 composite beads was treated in aqueous K2CO3 at room temperature to afford a mixture of metal carbonates and hydroxides on chitin or chitosan chain. |
