摘要:

磷是生物生长所需的营养元素,但也是造成水体富营养化的重要影响因素,是重要的水质污染指标之一。监测环境中不同形态的磷元素对了解环境污染状况、监测水质质量和保障人民健康安全具有重要意义。综述了监测水中总磷的前处理技术和检测方法,前处理技术包括不同的消解手段和磷预富集技术,总磷检测方法包括光谱法、色谱法、质谱法、电化学法、流动注射法。从工作原理、方法特点及实际应用等方面对各技术方法进行了阐述,并对其优缺点进行了评价。指出目前主流检测方法无法在复杂多变的检测环境中对总磷进行准确、稳定和实时的原位检测,并根据目前存在的问题对总磷检测方法未来的发展进行了前景展望,旨在为未来水质总磷新型高效绿色检测技术的开发提供参考和借鉴。

Abstract:

Phosphorus is the essential nutrient element for biological growth,and it is also a main reason causing water eutrophication,which is an important index in water pollution. Therefore,it is of great significance for analyzing environmental pollution,monitoring water quality and protecting people’s health and safety to monitor different forms of phosphorus in the environment. The pretreatment and detection methods of total phosphorus were discussed. The pretreatment techniques included different digestion methods and phosphorus preconcentration techniques,and the detection methods of total phosphorus included spectroscopy,chromatography,mass spectrometry,electrochemical method and flow injection method. The determination principles,method characteristics and application of method for determination of total phosphorus were introduced,and the advantages and disadvantages of these methods were evaluated. It was pointed out that the accuracy,stability and real-time detection of total phosphorus couldn’t be carried out by the current mainstream detection methods in the complex and changeable detection environment. In addition,the prospects of future technology development were discussed according to the current problems,aiming to provide reference for the development of efficient and new green detection technology of total phosphorus in water quality in the future.

Key words: total phosphorus, water quality, in-situ detection
