摘要
采用高温氧化-化学发光检测法（high temperature oxidation ＆ chemiluminescence, HTO-CL）进行水质总氮（TN）的在线测定。总氮浓度（CN）与化学发光的强度（IN）呈良好的线性关系，线性区间为0．05～100mg／L。对真实水样采用本方法进行测定，其结果与国标方法相符，回收率在90％～110％之间。以本方法为工作原理的TN-2000型总氮测定仪可用于地表水质及污水的在线监测。
On-line determination of total nitrogen in water by using the method of high temperature oxidation ＆ chemiluminescence was carried out. The detection limit is 0.05 mg/L（3σ）, the linerar range of determination is 0.2 - 100 mg/L. There isn＇t obviously different between instrument found and GB method found. The feasibility was tested using national standard solution. The Total Nitrogen Analyzer （TN-2000） based on the principle of high temperature oxidation ＆ chemiluminescence can be used in the on-line monitoring of surface water and waste water.
