Abstract: Aims: A novel dummy template molecularly imprinted bisphenol F monolithic bar was proposed for the microextraction of bisphenol A. It could avoid the leakage of bisphenol A in the trace analysis.
Methods: Bisphenol F was used as dummy template to prepare molecularly imprinted monolithic bar. The monolithic bar was synthesized in glass capillary with 1 mm diameter. And it was cut into 1.85 cm rods for sorptive extraction.
Results: The dummy template molecularly imprinted monolithic bar showed good selectivity to bisphenol A, bisphenol B ,bisphenol F, bisphenol S, and bisphenol AF. The imprinting factor was 1.7. The monolithic bar could used for microextraction of bisphenol A in water samples.
Conclusions: The dummy template molecularly imprinted monolithic bar was used for the bisphenol A analysis in sewage and pond water samples. The recoveries were 59.29-91.14% and 58.99-89.04%, respectively.
