<p> The major part of the present work dealt with adapting the
droplet technique to the study of nucleation from solution of some
analytically important metal chelates. Precipitation from homogenous solution was introduced as the means of gradually increasing the supersaturation in the droplets. This new method of producing supersaturation enabled the extention of the droplet technique to
nucleation studies of sparingly soluble substances. </p> <p> In addition, a second novel way of achieving supersaturation
in the droplets was devised. In contrast to the first method, which
increased the amount of solute at constant droplet volume, the second
method maintained the amount of solute constant, while gradually
reducing the volume of the droplet. This permitted studies on
nucleation from solution of soluble substances to be carried out
isothermally. </p> <p> The two techniques mentioned above were applied successfully
to the study of nucleation from solution of four analytically important
metal chelates and to several inorganic salts, respectively. </p> / Thesis / Doctor of Philosophy (PhD)
