چکیده انگلیسی
A molecularly imprinted polymer (MIP) obtained by precipitation polymerisation using propazine as template has been employed as sorbent for the solid phase extraction of triazines and some of their hydroxylated and dealkylated metabolites from river water. Three configurations were studied: (a) use of the propazine-MIP as a selective sorbent for the extraction of triazines directly from water; (b) use of mixtures of LiChrolut EN (a polymeric sorbent of styrene divinylbenzene) and propazine-MIP as sorbent, and (c) use of propazine-MIP as a clean-up sorbent for organic extracts obtained in a prior SPE procedure with LiChrolut EN. The former two configurations imply that the analytes pass through the propazine-MIP in aqueous medium, whereas in the latter case the analytes percolate through the propazine-MIP in an organic medium coming from the previous SPE step. Different types of water were tested to assess matrix effects. The analytical characteristics of the three configurations were evaluated.
