The binding of chrome violet, which is a monoazo dye and involves two hydroxyl groups in the o and 0 ' positions to an azo group, to chitin, and partially deacetylated chitin, was examined in the presence of metal ions. Zn2+ and Cu2+ ions do not perceptively influence the binding affinity of chrome
