Abstract : The work presented in this thesis includes: i. The retention profile antimony (III) from aqueous media onto rhodamine 6G treated PUFs was critically investigated. A dual-mode sorption mechanism involving absorption related to "solvent extraction" and an added component for "surface adsorption" is proposed for antimony (III) uptake. The kinetics, thermodynamic characteristics and the chromatographic separation of antimony (III) and (V) species by Rhodamine 6G treated PUFs were critically studied and properly assigned. Complete sorption of antimony (III) from industrial wastewater by the loaded PUFs packed columns was achieved. The sorbed antimony (III) species were quantitatively recovered with Aceton. ii. Developing of a low cost and sensitive differential pulse adsorptive cathodic stripping voltammetry (DP-CSV) method for ultra traces determination of antimony (III, V) using the reagent 4-(2-thiazolylazo) - resorcinol reagent (TAR). The method was based upon the adsorptive deposition of antimony (III) –TAR complex at hanging mercury drop electrode (HMDE), followed by the reduction of the adsorbed complex at -0.40 V versus Ag/AgCl reference electrode in B-R buffer of pH5.2. The dynamic range and the values of LOD and LOQ of the developed method were determined. The method was applied successfully for the analysis of antimony (III,V) in water samples. iii. The electrochemical behavior of the food color Erythrosin b in aqueous media in an attempt to develop a low cost (DP-CSV) method of the food colorant. The developed (DP-CSV) method was applied successfully for the analysis of the food colorant in commercial soft drinks and food samples with excellent recoveries.
