The HPLC chromatogram of different chlorophenol compounds under the same analyzing condition. The stationary phase was a reverse-phase poroshell 120 EC-C18 column. The mobile phase was a mixture of methanol and MillQ water (60:40 [vol/vol]) at a flow rate of 0.8 ml min−1. The injection volumes for all samples were 5 μl, respectively and the CPs were monitored at 210 nm. The retention time for phenol, 2-CP, 4-CP and 2,3-DiCP were as indicated in the figure, respectively
