A new cleanup process entitled ultrasonic assisted flat membrane liquid phase microextraction (UA-FM-LPME) was introduced. The UA-FM-LPME procedure in two phase format was applied for the extraction-preconcentration of malondialdehyde (MDA) as an analyte model from the biol. samples after a derivatization reaction. In the designed extraction setup, the simultaneous use of two flat sheet membranes and the application of ultrasonic radiation provided the efficient mass transfer of MDA into the acceptor phase in a short extraction time (2 min). The collected organic phase was then analyzed through Red-Green-Blue (RGB) image anal. and HPLC coupled with UV-visible spectroscopy (HPLC-UV/visible) as detection methods. The key parameters affecting the extraction process were studied and optimized. The effect of the sugaring out on the partition of MDA into the extraction phase was examined for the first time. Under optimal conditions, linearity was observed in the concentration range of 8-1000 ng mL-1 for HPLC, and 10-1000 ng mL-1 for RGB anal., with the coefficient of determination (R2) values >0.9973. The introduced method also offered satisfactory relative standard deviations (RSDs) <4.0%. In order to examine the reliability of the technique in complicated matrixes, three different biol. samples (urine, saliva and blood plasma) were analyzed and the acceptable results in terms of relative recoveries (89.7-102.4%) were obtained. The designed setup in combination with RGB anal. will provide a low-cost alternative technique for rapid determination of MDA in clin. diagnosis or biochem. anal. without the need to complex, time consuming and expensive anal. instruments.
