Determination of heavy metals in trace quantity has been have become a matter of significance. But because of their complex template and usually low concentration, it is quite difficult in different food and environmental media, and thus more responsive instrumental techniques or a preconcentration

step is required. In this regard, liquid–liquid microextraction, cloud point extraction, coprecipitation, ionexchange and solid phase extraction have been developed.  In present study we will develop different microextraction procedures which will be coupled with atomic absorption and UV/Visible spectrophotometers for heavy metal analysis in different samples. Therefore, the aims of the present research work are to develop new preconcentration methodologies with better analytical figure of merit i.e., limit of detection, limit of quantification, enhancement factor and relative standard deviation. The developed methodologies will be compatible with spectroscopic detections (i.e., UV/visible and atomic spectrometers).
