Abstract

A sample pretreatment by microwave-assisted extraction (MAE), microwave-assisted alkaline degradation (MAAD) and microwave-assisted saponification prior to the determination of PAHs, PCBs, triazines and cholesterol in diverse samples using GC, GC-MS and HPLC has been developed. When MAAD was coupled with MAE, the degradation of chlorinated pesticides and the extraction of PCBs analytes in the samples could be carried out simultaneously. Likewise, when MAAD and MAS were coupled with MAE, the degradation, saponification and extraction could be carried out simultaneously. In addition, a microwave-assisted derivatization (MAD) of fatty acids in edible oil, plasma and shark cartilage has been developed. The analytical results are satisfactory. The microwave-assisted sample pretreatment methods are rapid, labor and solvent saving, moreover, non-chlorinated organic solvents can be used.
