A Selective Solid-Phase Extraction and Preconcentration Method with Using Molecularly Imprinted Polymer for Determination of Piroxicam in Pharmaceutical Samples

A powerful sample cleanup procedure using molecularly imprinted polymer as a solid phase extraction material for the preconcentration of piroxicam in pharmaceutical samples has been developed. The optimized conditions for the preparation of molecularly imprinted polymer as a selective sorbent for the preconcentration of this drug were also studied. It is very important to note that a preconcentration factor of 1000 and retention capacity of 30.0 mg/g can be achieved. Recoveries up to 95% were accomplished for the analyte of interest from a pharmaceutical piroxicam capsule sample. All of these experiments were also performed with nonimprinted polymer.
