Complex formation studies of metal ion with electron rich species

Abstract

The thesis entitled Complex formation studies of metal ions with electron rich species is comprised of five chapters. newlineThe first chapter describes a general introduction of the subject matter. The very relevant matters include:and#61472; and#61472;a brief discussion of complexation of different complexing agents with metals. and#61472;utility of coloured complexes in developing new newlinespectrophotometric methods for determination of metal ions. newline and#61472;a brief discuss of metal ions of interest. and#61472;a brief introduction of solid phase extraction. and#61472;different types of solid phases for preconcentration of metal ions. and#61472;a list of references taken from the worldand#700;s leading scientific journals in the field. Chapter II describes a spectrophotometric method has been described for the quantitative analysis of uranyl ion in soil samples. The method is based on the chelation of uranyl ion with piroxicam to produce a yellow coloured complex in 1,4- dioxane-water medium at room temperature which absorbs maximally at 390 nm. Beer s law is obeyed in the concentration range of 6.75 × 10-2 9.45 × 10-1 µg mL-1 with apparent molar absorptivity and Sandell s sensitivity of 4.114 × 105 L mol-1cm-1 and 0.00066 and#61549;g/cm2/ 0.001 absorbance unit, respectively.
