Summary The determinations of phenol is studied by means of a carbon paste electrode modified with 10% sepiolite using DPV. A 10 min preconcentration step was performed at pH 1.5 under open circuit conditions. Measurements were made in another cell by DPV with ΔE=100 mV (sweep rate = 40 mV/s) in 0.02 mol/l KNO3 medium at pH 2. Detection limits (3 σ) of 30 ng/ml were achieved for determinations in orange, lemon and cola drinks.
