The method of determining ethylene glycol in the air of workplace was established by ion exchange resin XAD-7 adsorption-capillary column gas chromatography. Experimental results showed good linear relationship in the range of 0 mg / L ~ 1 116 mg / L and the lowest detection limit was 0. 88 mg / L. The minimum detectable concentration was 0. 11 mg / m3 when the sampling volume was 7. 5 L. The relative standard deviation( RSD) of standard solution of ethylene glycol was 1. 3%. The blank standard addition rec...
