Abstract

The main factors affecting the characteristics of precipitated nickel ammonium sulphate hexahydrate crystals from aqueous solution have been investigated. Over the range 20–35 Β°C, the crystal median size increases with temperature, but decreases with supersaturation. The size distribution is relatively unaffected by temperature, but becomes narrower at high supersaturations. The yield of crystalline precipitate is greatly increased when non‐stoichiometric ratios of reactants are employed due to the sharp decrease in the equilibrium solubility.

## 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
