【Abstract】 This work is performed on a spectrofluorimeter, which is equipped with two vertical polarizers in both the excitation and the emission light paths. The use of this technique can effectively suppress the effect of scattered light during synchronous scanning. A new method of polarization synchronous spectrofluorimetry for the simultaneous determination of chrysene, anthracene and perylene is described. The detection limit is nearly a fourfold decrease. The relative standard deviation is less than 3.1%.更多还原
