Abstract	:	A simple and reliable methods for the of determination of trace amounts of mercury (II) and cyanide ions in complicated matrices have been developed in this thesis. The use of β _ correction spectrophotometry method has the advantage of virtual freedom from interference from extraneous ions including excess of the chromogenic reagent. The two developed methods do not require complex pretreatment of chromatographic separations and/ or pre concentration of the analyte. The Kinetics and thermodynamic characteristics of PQ+.Cl- treated PUFs sorbent suggested the use of this sorbent in packed column for the chemical speciation of bismuth (III) and (V). The proposed method was simple and low cost for the separation and chemical speciation of trace and ultra trace concentrations of bismuth (ІІІ) & (V) ions in water. The PUFs packed column can be re used many times without decrease in its efficiency. The use of cloud point extraction (CPE) in the last chapter of this thesis provided a low cost and precise approach for the separation, preconcentration and subsequent determination of sunset yellow in foodstuff. The method was simple, inexpensive, selective, and sensitive and it could be used as an alternative approach to the HPLC technique in the analysis of such class of chemicals at ultra trace concentration.
