Abstract: The pretreatment digestion method for the determination of total nitrogen in water is renovated,and the oven digestion method is instead of the high temperature steam digestion method.The linear relationship,accuracy,precision,spike recovery rate,detection limit,etc.of the analysis results by two pretreatment methods are verified and compared.The results show that the oven digestion method can meet the requirements in quality.
