Simple Spectrophotometric Method for Determination of Paroxetine in Tablets Using 1,2-Naphthoquinone-4-Sulphonate as a Chromogenic Reagent
Figure 6
Limiting logarithmic plot for molar reactivity of PRX with NQS. C and A
are the concentration and absorbance, respectively. For generating the first
line , [NQS]: ; [PRX]:
0.3 10−5 − 2.04 10−5 M; Clark
and Lubs buffer solution (pH 9): 1 mL; temperature: 25 ± 5; reaction time: 10 minutes.
For generating the second line , [NQS]: 1.9 10−3 − 1.9 10 −2 M; [PRX]:
1.37 10−5 M. The
other conditions are the same as those employed in generating the first line.
