Abstract:
A novel method was proposed for the quantification of nitrite ion in aqueous samples by the combination of an advanced quantitative fluorescence model with ratiometric fluorescence indicator 2 , 3-diaminonaphthalene . The proposed method was tentatively applied to direct quantitative determination of nitrite ion in turbid environmental water samples containing both scatterers and absorbers; and its performance was thoroughly investigated and evaluated. Experimental results showed that the proposed method could realize accurate quantitative determination of nitrite ion in environmental water samples with recovery rates in the range of 90. 8%-103. 0%, which were comparable to the corresponding values of HPLC-DAD experiments. The limit of detection and limit of quantification of the proposed method were estimated to be 1 . 9 and 5. 8 nmo/L, respectively.
