Volatile organic compounds (VOCs), and other pollutants including heavy metals, semi volatile substances, radionuclides, and nitrate/nitrites are major pollutants of drinking water sources. VOCs are one of the most common contamination categories of drinking water resources in most parts of world.
In this work our effort is concentrated on a simple method of purification of water from VOCs. The results of our study show that boiling for two minutes a sample of water contaminated with VOCs would lose all its VOC.
To a 1L sample of ultra-pure water were added 50 µL 2.0 mg/mL of a standard sample of 60 common VOC water contaminants. The samples were heated at several temperatures including room temperature, 70°C, 90°C, and maintained for zero, one, two, and three minutes at boiling temperatures. After cooling the samples to room temperature they were analyzed for VOCs using EPA Method 524.2. The instrumentation consisted of a Solatek 72 Multi-Matrix Vial Autosampler, Tekmar 3100 Purge and Trap Concentrator, Perkin-Elmer Autosystem XL Gas Chromatography, and Turbomass Gold Mass-Spectrometer. Five point calibration curves were made to analysis the concentration of the samples.
