Abstract
The spontaneous precipitation of barium sulphate in aqueous solutions was followed by counting the 131Ba specific activity in the aqueous ph ase. The main advantages of this method were the increased sensitivity and the possibility of monitoring the process to a larger extent in c omparison with other techniques. Kinetics parameters including the siz e of the critical nucleus and the surface energy of the precipitating solid were estimated according to the model for polynuclear growth.
