Abstract

The electrochemical property of a water‐soluble anthraquinone, CI Acid Blue 25, was investigated in the presence of · ‐, ·· ‐ or ·‐cyclodextrin. Addition of cyclodextrin (CDx) reduced the redox potential of the dye in the order: · ‐ > ·‐ > ·‐CDx. Cyclic voltammography confirmed this behaviour. The suppression of the electrolytic reduction of the dye indicated that ·‐ or ·‐CDx interacted with it more than ·‐CDx. Spectrophotometric analysis also showed that ·‐CDx was capable of forming a complex with the dye. In addition, the electrolytic reduction improved the uptake of dye by nylon 6 in the presence of CDx.
