| 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. |
