Abstract

The invention discloses a method and a system for determining sulfide content in water body. The method for determining the sulfide content in the water body comprises the following steps: sampling the sulfide-containing water body, collecting the hydrogen sulfide gas through a chemical reaction; performing spectrum detection on the collected hydrogen sulfide gas, obtaining a hydrogen sulfide gas absorbance spectrum feedback optical signal; transiting the obtained hydrogen sulfide gas spectrum absorbance optical signal to a data signal; analyzing the hydrogen sulfide gas absorbance spectrum feedback data signal, drafting a work curve by taking the concentration of a standard sample as abscissa and taking the absorbance of the standard sample as ordinate, and calculating the sulfide content by determining the absorbance of the sample to be measured. By employing the system for determining the sulfide content in the water body, detection process is simple and fast, the detection result is accurate and reliable, the detection cost is low, analysis operation is simplified, analysis speed is increased, and analysis error is reduced.

Description

technical field [0001] The invention relates to a sulfide detection method, in particular to a method and system for measuring sulfide content in water bodies. Background technique [0002] Sulfides (sulfides) and similar compounds include a series of minerals combined with metal and semi-metal elements and S, Se, Te, As, Sb, Bi. There are about 350 kinds of minerals, sulfides account for more than 2 / 3, the others are selenides, tellurides, arsenides, and individual antimonides and bismuthides ). [0003] There are two main sources of sulfide in water quality: one is that the minerals in the water contain sulfide, and the other is that the wastewater discharged from leather, paper, chemical, printing and dyeing industries contains a large amount of sulfide. The level of sulfide content is an important index to measure the water quality, especially the quality of the ocean bottom environment. Studies have shown that the sulfide content in the sedimentary environment is pos...
