Abstract

The invention provides a detecting device with a high-efficiency absorbing function for sulfide in a mud sample. The detecting device comprises a detector, an experimental bench, a unit detecting device and a lifting device, wherein the experimental bench is fixedly arranged at the top end of the detector; the unit detecting device comprises reaction flasks; the reaction flasks are arranged on thelifting device. The detecting device disclosed by the invention has the advantages of compact structure and convenience in operation; reasonable layout of the unit detecting device can be realized bythe detector and the experimental bench; the stability of an integral structure is high; on one hand, occupied area of the device is reduced; on the other hand, four groups of unit detecting devicescan be simultaneously operated, so that the detection progress is accelerated; by using a stopping effect of plastic sieve plates, the absorbing effect of hydrogen sulfide gas is improved.

Description

technical field [0001] The invention relates to the technical field of sulfide detection devices, in particular to a sulfide detection device in mud samples with high-efficiency absorption function. Background technique [0002] Inorganic sulfides are produced during anaerobic decomposition of sulfur-containing organic matter in soil. Under the condition of reducing state, sulfate can also be acted by microorganisms to generate sulfide. When sulfide encounters acid, it will produce hydrogen sulfide, which is easy to dissipate into the air, causing odor and high toxicity. It can interact with cytochromes, oxidases and disulfide bonds in such substances in the human body, affect the oxidation process of cells, cause hypoxia in cells and tissues, and endanger human life. Therefore, sulfide is an important indicator for soil monitoring. [0003] The current methods for the determination of sulfide in soil and sediment in my country include iodometric method, ion selective ele...
