Alizarin Complexone on Nanocrystalline TiO2: A Heterogeneous Approach to Anion Sensing
Source abstract
Abstract
Abstract A novel, heterogeneous approach to “naked‐eye” colorimetric and spectrophotometric anion sensing is demonstrated, employing the molecular receptor alizarin complexone adsorbed onto a nanocrystalline, mesoporous TiO2 film. pH buffer action intrinsic to the TiO2 film allows dip sensing in aqueous solutions. This heterogeneous sensing system exhibits a high selectivity to F– and CN– anions, high sensitivity, a rapid response time, and excellent reusability.

26. It should be noted that increasing the concentration of fluoride or cyanide anion to 0.01 M led to a blue–purple coloration of the film and eventually to dye desorption.
