Abstract: | Fluorescence quenching of coumarine 440 in ethanol due to the presence in aqueous solution of hydrogen peroxide is reported here. The Stern-Volmer plot is very much linear and quencher concentration could easily be estimated. An optical sensor for the detection of aqueous hydrogen peroxide could thus be easily constructed using the dye solution. |
