4. Conclusions
In this paper, anewand simple direct ECLmethod was developed
for determination of naproxen in human urine. The ECL reaction
was well compatible with the mobile phase of HPLC. The proposed method
allowed for the sensitive determination of naproxen
in human urine samples, and offered wider linear range, lower
detection limit. Compared with the indirect ECL of Ru(bpy)3
2+ or
luminol, present method wasmore simple and convenient to operate.
