## Abstract A technique is described for rapidly assessing the effect of impurities on primary nucleation in solutions. The influence of Ca^2+^, Sr^2+^, Ba^2+^, Ag^+^, Pb^2+^, Cr^3+^ and Ni^2+^ on the nucleation of potassium sulphate solutions is discussed. It is generally observed that a discontin

## Abstract Gypsum (Calcium Sulphate Dihydrate) has been precipitated by mixing aqueous solutions of calcium chloride, sodium sulphate and sodium chloride at 25Β°C. In the absence of solid gypsum, classical nucleation theory predicts rates reasonably well only at the expense of some adjustable param
## Abstract In the present work, the effects of sulphate ions on the iron precipitation from aqueous solution were investigated. It was shown that sulphate ions delayed the iron precipitation when this ion was added in form of Na~2~SO~4~. This effect became less significant in presence of magnesium
