On-line solid phase
extraction and HPLC determination of phthalic acid monoesters by desorption
with subcritical water
Abstract
The possibility
of on-line solid phase extraction and HPLC determination of phthalic acid
monoesters is demonstrated. Hybrid procedure includes solid phase extrcation of
phthalates from 10 ml of water sample on porous graphitic sorbent Hypercarb,
desorption with subcritical water at 150°C, focusing of the analytes at the
initial part of the HPLC column and separation with water-acetonitrile mixture.
Key words: phthalates, solid phase extraction, subcritical
water, on-line coupling.
