Most samples are not suitable for direct introduction into
analytical instruments. For this reason, the sample preparation procedure is an important step in
an analytical study. However, selection of sample preparation procedure depends on the ana- lytes
properties, the matrix, concentration level of analytes in the sample, the analytical techniques to
be employed and their capabilities [1]. In the last two decades many extraction approaches for
minimizing the environmental pollution emphasis on reducing organic solvent consumption in
the extraction
process.
