摘要:
针对传统海水营养盐检测方法不能满足海水营养盐长期原位监测需求的问题，研制了一种基于分光光度法的多量程海水营养盐原位传感器检测系统，通过对系统的高度集成及对多量程检测、低功耗技术、漏液保护技术的应用，实现了对海水5项营养盐参数快速、宽范围、高精度的原位测量。经过实验室和青岛中苑码头现场测试，表明本营养盐传感器检测系统具有低功耗、高可靠性能，可满足对5项营养盐参数的快速精确测量要求，实现了对海水营养盐参数的原位监测，为相关部门及时了解海洋生态环境和水体富营养化程度提供了数据支持，具有重大现实意义。

Abstract:
Traditional methods cannot satisfy the long-term in-situ monitoring demands of seawater nutrient salt detection. In this work, a multi-range seawater nutrient salt in-situ sensor detection system based on spectrophotometry was developed.The system was highly integrated with multi-range detection, low power consumption, and liquid leakage protection. Study results showed that this system provided fast-parameter, wide-ranging, high-precision in-situ measurements of five nutrient salt parameters in seawater. Field testing by the laboratory and the Qingdao Zhongyuan Wharf showed that the sensor detection system was highly reliable, satisfied the fast and accurate requirements for measurements of five nutrient parameters, and produced in-situ monitoring of seawater nutrient parameters. The system provided timely data toward an understanding of the marine ecological environment and the degree of eutrophication of water bodies.
