|Abstract: ||The contents of this thesis describes the development of an
analytical method to determine the chemical speciation of heavy metals in
soils contaminted by sewage sludge and distillery wastes.
Chapter one serves as an introduction discussing the various heavy
metal species that can occur in soils. The chapter also contains a review
of the analytical methods that have already been used in speciation
studies and discusses their suitability for this particular problem.
Chapter two is mainly concerned with the derivation of a
relationship between the electrical conductivity and ionic strength of
Chapter three describes the development of suitable sampling
techniques for the study of chemical speciation in soils.
Chapter four describes rhe development of the size Exclusion
Chromatography (SEC) separation technique chosen to separate the species
The chapter also describes how this technique was interfaced
to Graphite Furnace Atomic Absorption Spectrometry in order to detect the
copper content of the various soil solution species.
Chapter five extends the above technique to the studv of the long
term partioning of copper in water extracts of sewage sludge and
distillery waste polluted soils and compares the results with those
obtained from previous studies on the same sampling sites.
Chapter six investigates the possibility of utilizing Inductively
Coupled Plasma Optical Emission Spectrometry as a detector for the SEC
Chapter seven contains suggestions for future research.|
