Automatic analyzing instrument of sulphide, phenolic compounds, anionic detergents and aniline in seawater

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 ...

The applicant of this patent application has submitted to the Patent Office of my country Intellectual Property Office the automatic analysis method of sulfide in seawater (publication number: CN101101264), the automatic analysis method of phenolic compounds in seawater (publication number: CN101187637), the anion in seawater Four patent applications for the automatic analysis method of detergent (publication number: CN101241079) and the automatic analysis method for aniline in seawater (publication number: CN101349650), although these four patent applications involve the flow path structure of the analytical instrument used, but the The instrument can only be used to analyze one pollutant in seawater, sulfide, phenolic compound, anionic detergent and aniline, but cannot simultaneously analyze four pollutants in seawater: sulfide, phenolic compound, anionic detergent and aniline , and the water harvesting system that should be set up for on-line (on-site) automatic analysis is not disclosed, so it takes a long time to obtain the analysis results of the four pollutants in seawater, sulfide, phenolic compounds, anionic detergent and aniline, and the operation is complicated
