| Abstract: | First order derivative synchronous fluorescencezero crossing method was used for the simultaneous determination of benzo(a) pyrene and benzo(k) fluoranthene.The relative standard deviation was less than 8 per cent for synthetic samples.The recoveries of benzo(a) pyrene and benzo(k) fluoranthene are in the range of 86.8-87.2 per cent,82.8-84.7 per cent respectively.This method has been applied to the simultaneous determination of Benzo(a) pyrene and Benzo(k) fluoranthene in water samples with satisfactory results. |
