“…Considerable interest has been shown in procedures for the determination of cyanide. Serfass and Muraca (216) reported a method which distinguishes between total and free cyanides. For total cyanide the sample is refluxed with sulfuric acid and cupric chloride.…”

1677At hlgh acidities, thiocyanate reacts wlth nitrate or other oxidants to produca free cyanlde. For thiocyanate-contalnlng wastewaters, a total cyanide procedure is reported based on use of EDTA at pH 4.0, acetate buffered, to dlsrupt the complexes of cadmlirm, chromium, copper, Iron, nlckel, and rlnc. NRrlte Interference is obvlated by adding sulfamic acid to the sample. Sulfldos are removed from the sample by lnltlal treatment with cadmium carbonate and, If necessary, from dlstliiates wlth aadmlum nitrate.
