针对目前国家标准分析方法检测水质总磷的技术不足，提出一种常温常压条件下基于超声辅助Fenton试剂消解样品与光谱分析的水质总磷快速测定方法，设计了在线分析实验系统，研究了测定实验方法与技术，针对实际环境水样，展开了与国家标准分析方法的现场对比测试实验，实验结果表明该消解方法在13.5 min内即可达到国家标准分析方法的消解率（97％～100％），检测周期为16 min ，解决了现有国家标准分析方法存在的技术不足，对水质总磷快速在线监测仪器的研发提供了重要的实验基础与技术支持。

Aiming at the technological shortage of national standard method for the determination of total phosphorus ,a rapid determination method of total phosphorus based on ultrasonic assisted sample digestion-spectrum analysis was put forward ,and the on-line analysis experiment system was designed .Relying on the experiment system ,the experimental method and technolo-gy was studied .In view of the actual environmental water samples ,contrast test experiment with the national standard method for determination method of total phosphorus was carried on .The experimental results showed that the digestion rate of ultra-sonic assisted sample digestion using fenton reagents could reach 97% ~100% in 13.5 minutes ,and the determination method could complete one copy of sample analysis within 16 minutes .This determination method can solve national standard method’s technical problems .All of this research work provides the important experimental basis and technical support for the develop-ment of the rapid on-line monitoring instrument for determination of total phosphorus .
