| Abstract: |
| A method was developed to determine 10 nitrobenzene compounds in water directly by high performance liquid chromatography. C18 was used as the separated column， and UV detection was set at the wavelength of 254 nm. A mixture of methanol and water was employed as the mobile phase. Methanol and water was mixed at the volume ratio of 9：1 in the pretreatment， and the sample was filtered through microfiltration membrane followed with high performance liquid chromatography analysis. The detection limits of 10 nitrobenzene compounds were in the range of 4.3~5.5μg/L. Values of recovery were in the range of 79%~136% with RSDs of 6.8%~13%， which met the requirements of monitoring. |
