Objective To establish a new detection method of high efficiency,practical and environmental protection.Methods 3 kinds of phenolic compounds were studied by solid phase extraction and high performance liquid chromatography（ HPLC）,and the detection conditions and technical indexes（ linear correlation coefficient,detection limit,recovery rate and precision,etc.） were studied.Results The linear correlation coefficient was above 0.999 9,the detection limit was 0.08μg/L,0.04 μg/L,0.02 μg/L,the recovery rates were 97.5%-116.9%,94.4%-120%,87.3%-118.7%,RSD = 2.1%-2.7%,2.2%-2.6%,2%-2.3%. Conclusion The new method,high sensitivity,low toxicity and environmental protection,has a high practical for the national standard for the detection of phenols in water.
