Application
Ethyl 4-hydroxybenzoate (ethylparaben) was used to study the in-situ derivatisation solid-phase microextraction procedure for determining parabens, related chlorophenols, and triclosan in water.
Ethyl 4-hydroxybenzoate, 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.
