into the separation of metal silver from industrial wastewater using
electrochemical cell was carried out. Wastewater from photo laboratories was
collected and treated batch wise using electrolytic equipment. A constant
voltage of 2.0 V and variable current in the range of 0.3 - 0.6 A at normal
temperature were passed through the electrolyte for a period from 0.25 - 1.0 h.
The results showed that increase in current yield an increase in the amount of
metallic silver recovered with highest values of 2.3 g and 2.8 g at 0.6 A for
the tested samples 1 and 2, respectively. The electrochemical separation method
proved to be more reliable and economical when compared to other methods and
also, reduction in environmental pollution of industrial wastewater containing
high concentration of silver metal is achieved.
