Ethyl 4-hydroxybenzoate (ethylparaben) was used to study the in-situderivatisation solid-phase microextraction procedure for determining parabens, related chlorophenols and triclosan in water. It is a novel sorbent for solid-phase extraction, was used to study its retention property. It has high extraction efficiency towards the compounds tested owing to the electrostatic interaction, hydrophobic interaction and hydrogen bonding.
