Contamination of drinking water by arsenic is a worldwide phenomenon needing and receiving the greatest attention in this century. In this work, a novel Fluorescence Resonance Energy Transfer (FRET) based ratiometric sensor for detecting arsenic(v) was demonstrated. In this system, Acriflavine acted as energy donor, while Rhodamine B acted as energy acceptor. In the presence of arsenic(v) the FRET efficiency increases almost linearly in the range of 0.04-0.09 mg/L. Based on these analysis a simple and highly sensitive method for the detection of arsenic(v) has been demonstrated with the detection limit (LOD) of 10 mu g/L. The applicability of the planned method has also been tested using natural lake water with satisfactory results.
