Analytical methods of preserving and identifying cyanide and thiocyanate in coal gasification wastewaters are developed. Aqueous reaction pathways leading to the formation of thiocyanate from cyanide are investigated. Results may be useful to predict or explain quality changes in such wastewaters. Attempts to engineer the reactions may largely entail sulfide oxidation kinetic control. (2 diagrams, 7 graphs, 22 references, 62 tables)
