Automatic Detection and Analysis of Polar Volatile Organic Compounds in Industrial Wastewater Using Ultrasound Coupled Solid-Phase Microeztraction
This report presents a novel system, which continuously monitors polar volatile organic compounds (VOCs) in industrial wastewater. The system utilizes an ultrasound coupled autosampler, headspace solid-phase microextraction (HS-SPME), and a gas chromatography/flame ionization detection GC/FID for onsite, real-time detection and quantification of VOCs. The system was first extensively validated in the laboratory, and then brought to a wastewater treatment plant for further experimentations. A mobile station has been setup for the field experiments. The construction of the mobile station aims to provide a platform for continuous, real-time automatic data collection. In the field experiments, six VOCs have been successfully detected and quantified. The data have shown that the system exhibits a good linearity with a relative standard deviation (RSD) to the calibration smaller than 15%, a recovery rate above 90%, a precision between 6.5% and 11.5%, and the method detection limit (MDL) between 3.19ppb and 7.57ppb. Experiments have further demonstrated the successful use of ultrasound to accelerate sample equilibrium for HS-SPME fiber.
