This paper prensents the chromatography analysis condition study on the main poluted compozotion(furaldehyde and furfuran) in polytetrahydrofuran waste water with HPLC-DAD. Given the chromatography condition is that ODS is the stationary phase, the mix liquid in which methenyl:water = 75:25 is the mobile phase, the flow is 1.00 mL•min-1, using diode array detector(detect wavelength when furaldehyde is 274 nm and furfuran in 208nm), the injection volume is 2.0µL, the column temperature is 25.0°C. This paper presents the study of treatment of polytetrahydrofuran waste water by active carbon adsorption, investigates the three conditions of the amount of active carbon, stirring time and absorption temprature, and confirms that the best absorption condition is that the amount of active carbon is 3.0g, stirring for 30min and room temprature 20°C. |
