| Abstract | ||
| Excitation of phenoxazine in aqueous solution exhibits a very low fluorescence intensity because this compound has not a large conjugated π-bonds system as well as, it is a planar compound. Fluorescence of phenoxazine at 405 nm was found to be greatly enhanced in miceller medium of hexa decyl trimethyl ammonium bromide. Beer's law was found to be obeyed in the concentration range of 50-500 ng.ml-1 and the detection limit (LD) was 4.9 ng.ml-1.The method was successfully applied for the determination of low concentration of phenoxazine in spiked drinking and irrigation water without any pre-treatment. | ||
