ABSTRACT

Under neutral or acidic conditions, it may further oxidize to CO2 and N2. e analysis of cyanate is based on its total conversion to an ammo-

nium salt. is is achieved by heating the acidi ed sample. e reaction is shown below:

2 4 2 4 2 4 32KCNO H SO 4H O (NH ) SO 2KHCO+ + → +

e concentration of ammonia (or ammonium) minus nitrogen before and a er the acid hydrolysis is measured and the cyanate amount is calculated as equivalent to this di erence.
