Abstract

Amongst organophosphate pesticides, the one most widely used and common environmental contaminant is DIAZINON; thus methods for its trace analysis in environmental samples must be developed. Use of DIAZINON imprinted polymers such as sorbents in solid phase extraction, is a prominent and novel application area of molecular imprinted polymers. For DIAZINON extraction, high performance liquid chromatography analysis was demonstrated in this study. During optimization of the molecular imprinted solid phase extraction procedure for efficient solid phase extraction of DIAZINON, PLACKETT-BURMAN DESIGN was conducted. Eight experimental factors with critical influence on molecular imprinted solid phase extraction performance were selected, and 12 different experimental runs based on PLACKETT-BURMAN DESIGN were carried out. The applicability of DIAZINON imprinted polymers as the sorbent in solid phase extraction, presented obtained good recoveries of DIAZINON from LC-grade water. An increase in pH caused an increase in the recovery on molecular imprinted solid phase extraction. From these results, the optimal molecular imprinted solid phase extraction procedure was as follows: solid phase extraction packing with 100 mg DIAZINON imprinted polymers; conditioning with 5 mL of methanol and 6 mL of LC-grade water; sample loading containing DIAZINON (pH=10); washing with 1 mL of LC-grade water, 1 mL LC- grade water containing 30% acetonitrile and 0.5 mL of acetonitrile, respectively; eluting with 1 mL of methanol containing 2% acetic acid. The percentage recoveries obtained by the optimized molecular imprinted solid phase extraction were more than 90% with drinking water spiked at different trace levels of DIAZINON. Generally speaking, the molecular imprinted solid phase extraction procedure and subsequent high performance liquid chromatography analysis can be a relatively fast and proper approach for qualitative and quantitative analysis of DIAZINON in drinking water.
