Metastable Zone

The metastable zone width has been determined for pure KCl-H2O and three compositions of the ternary system KCl-KBr-H2O at temperatures close to 35 and 40 °C. In agreement with literature it was confirmed that there are two different regions of solid solutions in the system KCl-KBr-H2O. The data on metastable zone width show a different crystallization behaviour of both of the solutions: the values of critical nucleation parameters calculated from the measurements exhibit a distinct asymetry which may be connected with different radii of the Cl- and Br- ions.

Concentration Of Impurities

When snow is made from sewage effluent, the impurities become concentrated in the early melt leaving the later runoff relatively pure. This could provide a low cost method of separating nutrients from secondary sewage effluent. Laboratory experiments showed that the degree of concentration was largely independent of the number of melt freeze cycles or initial concentration of impurity in the snow. The first 20% of melt removed with it 65% of the phosphorus and 90% of the nitrogen from snow made from sewage effluent; and over 90% of potassium chloride from snow made from potassium chloride solution. Field experiments with a salt solution confirmed the laboratory results.

The Given

The metastable zone width of an aqueous solution of KCI was measured as a function of the time and temperature of overheating above the equilibrium solubility temperature. It has been found that when the experiments follow close upon one another, the parameters of the preceding experiment affect the results of the experiment to follow.The results are interpreted in terms of hypotheses advanced in the literature to account for the effect of thermal history of solution. The plausibility and applicability of these hypotheses are assessed for the given cause of aqueous solution of a well soluble electrolyte.
