Abstract
A low cost metal replacement method has been used to determine the optimum conditions for
silver recovery in photographic fixer received from different clinics. The chosen experimental parameters and
their range were (i) pH 3- 5, (ii) reaction time 1-7 days, (iii) different metals and metal alloys and (iv) suitable
acid at concentration 10% (in weight). The silver concentration in the manageable fixer solution should be ≤ 5
mg/ L. The method by using these optimum conditions is particularly suited for treating the fixer solution in a
manner which enables to considerable reduction in cost of silver recovery and reduced environmental pollution
