Abstract

The invention relates to an automatic analyzing instrument of sulphide, phenolic compound, anionic detergent and aniline in seawater, characterized by comprising a water mining and shunting system, four mutually independent flowing paths and a data-processing system. The water mining and shunting system is connected with the four mutually independent flowing paths by pipe fittings and respectively conveys standard sample or test sample for detecting sulphide, phenolic compound, anionic detergent and aniline to the four mutually independent flowing paths; and detectors in the four mutually independent flowing paths are respectively connected with the data-processing system and respectively convey detection result signals of the sulphide, the phenolic compound, the anionic detergent and theaniline in the standard sample or the test sample to the data-processing system to be processed, stored and displayed. The instrument can carry out the simultaneous online automatic analysis of sulphide, phenolic compound, anionic detergent and aniline in seawater and simultaneously acquire detection results of the four pollutants after one test sample is input.

Description

technical field [0001] The invention relates to an automatic analysis instrument for sulfide, phenolic compound, anionic detergent and aniline in seawater. Background technique [0002] In recent years, marine environmental pollution has become increasingly serious. The content of sulfides, volatile phenols, anionic detergents and aniline in the ocean is increasing year by year, affecting the normal reproduction of marine organisms and causing harm and potential impact on human health. Due to the complex seawater matrix, serious interference, and very low content of the above four substances, analysis is very difficult. [0003] Regarding the analysis methods and instruments of sulfides, phenolic compounds, anionic detergents and aniline, although domestic and foreign scholars have carried out a lot of research work, most of them are used for the analysis of surface water and industrial sewage. The national standards for the analysis of sulfides, volatile phenols, anionic ...
