- •
Pb(II) and Co(II) traces have been determined in tap water and foods samples.
- •
8-Hydroxyquinolein is used to derivatize metals in fluorescent compounds.
- •
Filter papers are used as support for Pb(II) complex selective retention.
- •
The methodology showed good reproducibility with low operational cost.
