Özet
Pesticides are harmful compounds even in trace levels for human health, so the importance of determination of these compounds is increasing day by day. Magnetite-molecularly imprinted polymer and high resolution liquid chromatography has been combined for the preconcentration and sensitive and selective determination of trace levels of pirimicarb. the developed method appeared to be rapid since the total procedure for detection of pirimicarb can be completed within one hour. the magnetic polymer is reusable and the same polymer can be used at least ten cycles for detection of pirimicarb. Limit of detection (LOD) of the method was found to be 1.60 mu g L-1 within the linear range of 7.5-250 mu g L-1. Proposed method has been applied to water and apple samples and quantitative recovery values were obtained. the proposed method appeared to be suitable for both preconcentration and determination of trace levels of pirimicarb by combining the selectivity of the reusable imprinted polymer with the high sensitivity of liquid chromatography-quadrupole-time-of-flight mass spectrometry. Magnetite-molecularly imprinted polymer combined with high resolution chromatography has been used for the first time for the determination of pirimicarb.
