title: A highly selective dual mode detection of Fe3+ ion sensing based on 1,5-dihydroxyanthraquinone in the presence of β-cyclodextrin.
abstract: 1,5-Dihydroxyanthraquinone (1,5-DHAQ) and in the presence of β-cyclodextrin (β-CD) has been used to find Fe(3+) ion in aqueous solution by UV-visible and fluorescence spectroscopy. The chromo-fluorogenic probe undergoes absorption and emission intensity enhancement upon binding to Fe(3+) ion in pH~7 aqueous solutions. The enhancement of the chemosensor probe is attributed to a 1:1 inclusion complex formation between β-CD and 1,5-DHAQ, which has been utilized as the basis for selective detection of Fe(3+) ion. The chemosensors can be applied to the selectivity and sensitivity analysis which showed that the remarkable sensing limit of detection (LOD) was 7.3∗10(-7)M (β-CD/1,5-DHAQ:Fe(3+)). The proposed chemosensors based on 1,5-DHAQ and in the presence of β-CD has a good selectivity, sensitivity and potential application to the determination of Fe(3+) ion in environmental and biological systems.
