Popis:	Pyrogallol is determined by means of chemiluminescence at 500 nm which accompanies the oxidation by hydrogen peroxide of autoxidized pyrogallol in the presence of chromium(III) and formaldehyde. Using air-segmented continuous flow analysis, the LOD (3s) was 6.0 × 10–9 mol dm–3 and the calibration was linear up to 10–4 mol dm–3. The method has the potential to be extended to other phenols.
