- Preview. Full text. Silver extraction from photographic waste Introduction: During the photographic film processing, Silver leaches into the fixer solution (Sodium Thio-Sulphate) from the photographic film and forms Silver Thio-Sulphate complex ions. The fixer is considered exhausted after becoming silver-rich (7-10 gm/l), as it can no more serve the purpose of fixing …

- The results showed that the mobile carrier Cyanex 302 is selective towards silver compared to the other metals in the photographic waste. The highest silver extraction is obtained by using 0.05 M Cyanex 302, 3% (w/v) Span 80, 4.166 Hz (250 rpm) stirring speed, 1.0 M thiourea in 1.0 M H 2 SO 4 stripping agent, 1:5 of treat ratio, and kerosene as a diluent.
