摘要：
Polymeric capillary tubing has been used to concentrate polycyclic aromatic hydrocarbons (PAH) initially present in spiked water samples at the part per million level. An aqueous sample containing PAH is pumped through uncoated capillary tubing and PAH are adsorbed on the inner surface of the tubing. The PAH are then desorbed using a small quantity of organic solvent. Ethyl vinyl acetate and polyethylene capillary tubing materials, the effect of temperature on adsorption and the nature of the organic solvent for desorption were studied.
