Abstract:
A method for DMF in waste water and organic phase with high performance liquid chromatography ( HPLC) was established. HPLC was performed on a Krornasil-C18 column,using methanol and water ( 15∶ 85) as mobile phase and the detection wavelength of 205 nm. The results show that the calibration curve is linear in the range of 3. 06 mg /L - 38. 28 mg /L for concentration of DMF ( r = 0. 999 7) ,precision is high,and its relative standard deviation is 1. 03%. The recovery DMF is between 99. 86% - 101. 09%. The method is rapid,accurate,reproducible and can be used for quantitative analysis of DMF in wastewater and provided as a good central control analysis method of recycling conditions of wastewater.
