I have tried hydrolysis with KOH then titrating the Cyanide Ions liberated with Silver Nitrating but I am not getting results. Anyone with a better method please help. I'll be very grateful since I don't have access to a HPLC.
First try on spectrophotometer if you don't have access to spectrophotometer, then try non-aqueous titration with 0.1N perchloric acid. Use mercuric acetate in solvent for interference of chlorides.
