Özet

The aim of the present work is to submit an investigation on the optimum conditions of crystallization of silver nitrate salt from saturated silver nitrate solution in nitric acid. The saturated solutions of AgNO3 at 70 degreesC obtained by evaporation of dilute silver nitrate solutions with nitric acid were crystallyzied in a jacketed glass vessel with controlled cooling. The parameters for the crystallization operation were chosen as stirring speed and crystallization period. For each experiment, crystals obtained from operations were filtered, washed, dried, and their photographs were taken before particle size analysis. The differential and cumulative analysis and produce yield calculations showed that the optimum values of the parameter for the crystallization of silver nitrate salt from saturated silver nitrate solutions with nitric acid were determined as 500 rpm stirring speed and 240 min crystallization period, with the highest yield.
