| Abstract | Complex cyanides (ferro-and ferricyanide) in industrial waste water effluents impose a direct threat upon the environment. Methods to recover or destroy these compounds were evaluated in laboratory studies. The techniques tested include electrolysis, ozonation, chlorination and heavy metal ion precipitation. The study was conducted to determine the feasibility of using one or more of these methods to reduce the concentration of ferricyanide in both concentrated (10,000 to 100,000 mg/l) and dilute (10 to 100 mg/l) waste effluents. A process for treating overflow photographic color process bleaches is described. (Modified author abstract) |
