This report presents a review of known cyanide destruction technologies with respect to applicability, feasibility, effectiveness, and cost. Particular emphasis was placed on the destruction of complex cyanides. Laboratory studies were conducted to evaluate a photocatalytic process to convert simple cyanides, iron cyanides and thiocyanates to cyanate using (TiO/sub 2/) and ultraviolet radiation. The scope of the problem of cyanide in waste water or leachate and the effectiveness of twelve different technologies that have been applied to the destruction of cyanide were assessed by review of available literature and discussions with industry and government authorities. Brief summaries of the problem and the current technologies are contained in the report. In general, the primary concern with cyanide effluent is its propensity to form complexes difficult to remove and that can later break down to highly toxic forms.
