Headspace Sorptive Extraction of Sulfur Compounds in Water

Article

Chemists from Wuhan University (Wuhan, China) used a headspace sorptive extraction technique based on a coated glass bar to determine volatile organic sulfur compounds in water.

Chemists from Wuhan University (Wuhan, China) used a headspace sorptive extraction technique based on a coated glass bar to determine volatile organic sulfur compounds in water. The glass bar was coated with a polyethylene glycol-polydimethylsiloxane-poly(vinyl alcohol) combination using a sol-gel approach. The sorptive bar was desorbed after extraction with ethanol. The researchers analyzed the extract using a large volume injection method with gas chromatography and flame photometric detection. They were able to complete more than 50 extractions without loss.
