Nitrate ion can be determined as ammonia by widely different reductive methods. Generally alkaline rccluction is employed, the DEWARDA-method being most commonly used. A general disadvantage of these methods is that the overdistilling of the hydroxide may often cause significant errors. COTTE AND KA
