nm, irradiating at lexc287 nm. The equation for
the calibration curve is: IABC, where I is the
fluorescence intensity (in arbitrary units). After
least-squares linear fit of the fluorescence emission
data (Table 1), we obtained A5(3), B41.2(9),
Cconcentration of diclofenac in mg l1, r2
0.995, n33 (three replicates of 11 points). Calibration
data and relative standard deviations
(RSD %) are given in Table 1. The detection limit
(DL, calculated as 3sA:B), was 0.2 mg l1.
