“…The triazophos standard solution of different volumes were added into 10 mL brown volumetric flask respectively, and 7 samples of prediction set were obtained by adding duck meat extract to 10 mL. (6) The prepared samples were loaded into quartz cuvette, and three-dimensional fluorescence spectra were obtained by using spectrofluorophotometer. The parameters of spectrofluorophotometer were set as follows: the range of the excitation wavelength was 230～270nm, the range of the emission wavelength was 240～ 500nm, and the excitation and emission slits are all 5nm.…”

The triazophos is a kind of organic phosphorus pesticide, the quantitative determination model based on three-dimensional fluorescence spectroscopy coupled with alternating trilinear decomposition (ATLD) was explored for realizing the rapid determination of triazophos content in duck meat. Firstly, three-dimensional fluorescence spectra of duck meat extract, triazophos standard solution and duck meat extract containing triazophos were explored, respectively. Secondly, the fluorescence quenching phenomenon of the triazophos in duck meat extract was analyzed. Lastly, the number of components for three linear decomposition of ATLD was set as 2 by using the core consistency diagnostic, and the calibration curve between the relative fluorescence intensity and the actual concentration of the triazophos was established by using ATLD. The experimental results showed that the determination coefficient (R2) and the root mean squared error of prediction (RMSEP) for the proposed model in this paper were 0.9741 and 0.764 respectively, and it was feasible to predict the triazophos content in duck meat combining with three-demensional fluorescence spectroscopy and ATLD.
