Abstract
Activated charcoal, Amberlite XAD-2 and XAD-7 were evaluated as solid sorbents for air sampling of isopropyl glycidyl ether (IGE), allyl glycidyl ether (AGE), n-butyl glycidyl ether (BGE), phenyl glycidyl ether (PGE) and o-cresyl glycidyl ether (CGE). IGE, AGE and BGE were determined by capillary gas chromatography and flame ionization detection, PGE and CGE by high-performance liquid chromatography and ultraviolet detection. Amberlite XAD-7 was the best sorbent for all glycidyl ethers except IGE, which showed insufficient retention on this sorbent. Activated charcoal gave good recoveries only for IGE, AGE and BGE. The storage stability was acceptable on all three sorbents, and relative humidity had little effect on retention and recovery.
