Detection structure and method for chromium (VI) in water

Abstract

The invention relates to the field of detection and especially relates to a detection structure and a method for chromium (VI) in water. The structure includes a sampling tube provided with a tube mouth. The outer side of the tube mouth is provided with upper threads. The tube mouth also includes a plug-in part, which includes a ring of edge enclosing structure, of which the middle is the plug-inpart. The middle part of the plug-in part includes a filter structure. A groove is formed between the edge enclosing structure and the plug-in part, so that the tube mouth can be inserted into the groove. The surface, towards to the tube mouth, of the edge enclosing structure has threads, so that the edge enclosing structure can be installed on the tube mouth through the threads. The method includes the steps of: quick pretreatment of suspension substances: pouring the sampled water from the filter structure in the plug-in part, so that gas penetrates through the filter structure upwardly andsuspension substances are filtered away when the water enters the sampling tube, wherein liquid, which is free of suspension particles and can be processed directly, remains in the lower part; and measuring the chromium (VI). The structure can greatly reduce settlement time of the suspension particles and is shorter in treatment time, is convenient to use in detection and allows reagent addition.

Description

technical field [0001] The invention relates to the field of determination, in particular to a structure and method for determining water quality hexavalent chromium. Background technique [0002] The sample does not contain suspended solids, and the clean surface water with low chroma can be directly measured; if there are particles, it must be precipitated, so each measurement must wait a lot of time. Contents of the invention [0003] Purpose of the invention: In order to provide a better water quality hexavalent chromium determination structure and method, the specific purpose can be seen in the multiple substantive technical effects of the specific implementation part. [0004] In order to achieve the above object, the present invention takes the following technical solutions: [0005] Option One: [0006] The determination structure of water quality hexavalent chromium is characterized in that it includes a sampling tube, the sampling tube includes a nozzle, the ou...
