Abstract:
Objective To establish a method for determination of trace phenol in waste water. Methods It is reported that trace amounts of phenol can inhibit the decoloring reaction of methyl red by potassium bromate in dilute sulfuric acid medium. Results The linear range of this method was 0-17 ?g/25 ml for phenol with detection limit of 6.53?10-9 g/ml, RSD was 0.96%-1.70%, recovery rate was 97.8%-102.0%. Conclusion The proposed method is simple, sensitive and can be applied to determine trace phenol in waste water with satisfactory results.
