Abstract:
Objective To establish a quick,simple and high_efficiency_low_consuming RP_HPLC method to test phenol,benzenediol and benzenetriol in environmental waters.Methods Applying SPE technology to treat,to separate samples,phenolic compounds in water were determined by RP_HPLC.Results The analytical conditions for phenol were selected as wave length 270 nm and flow rate 0.5 ml/min.Linear scope ranged from 0.1 to 10 ?g/L,precision ranged from 0.012 to 0.057(RSD),accuracy ranged from 98.3% to 106%(recovery rate) with detection limit at 0.1 ?g/L.At the same time research was done on m_benzenediol(resorcinol)?o_benzenediol(pyrocatechol)?p_benzenediol(hydroquihone)?benzenetriol with detection limits at 0.11?0.13?0.11?0.14 ?g/L respectively.Conclusion This method was simple and quick to operate.The analytical methods of phenol,benzendiol and benzenetriol had advantages with high accuracy?sensitivity and selectivity.
