Abstract:
This thesis describes a systematic investigation of the thermodynamic quantities associated with the interaction between Cu2+ and SO42- in aqueous solution. A variety of techniques including UV-Visible spectrophotometry, Cu(II) ion-selective electrode potentiometry, dielectric relaxation spectroscopy and titration calorimetry have been used. The values for the (aq) association constants determined by UV-Vis spectrophotometry in NaClO4 media as a function of ionic strength were in good agreement with published data but were lower than the values obtained from Cu(II) ion -selective electr

Abstract:
Kinetic studies, as well as the thermodynamics of the formation of the Cu(II)-Pyridine-2-azo-p-dimethylaniline complex ion in aqueous solutions, and in the presence of sodium dodecyl sulfate (SDS) are reported. The kinetic determinations of the formation of complex were performed using the temperature jump technique. The rate constants in the forward (k$\rm \sb{f}$) and backward (k$\rm\sb{b}$) directions had values of (2.10 $\pm$ 0.97) $\times\ 10\sp7$ scM$\rm \sp{-1}s\sp{-1}$ and (10.0 $\pm$ 0.35) $\rm \times\ 10\sp{2}\ \sb{s}\sp{-1}$ respectively in aqueous solution at 25$\sp\circ$C.

For Alanine (NH2CHCH3COOH) as a model ligand, the effects of Cu(I) quantum yields in different conditions (changing pH, copper and ligand concentration, and ionic strength) were discussed. In order to know the trend of photoreactivity of copper-amino acid complexes, the rest eight amino acids with non-polar side chains have also studied.

Chitosan is from the deacetylation of Chitin. It has a very good absorption, can be used in environment and also can use to absorb heavy metal ions from solution. Chitosan is easy to have coordination bond with metal ions by sequestration. Chitin structure is similar to cellulose which is abundant on earth. Chitin can be extracted from shrimps, crabs and much more. It was found to be the se
