Abstract

The invention provides a detection reagent for a wading pipe as well as a preparation method and a detection method of the detection reagent, and relates to the technical field of pipe detection. Thedetection reagent comprises the following components: a sodium bicarbonate solution, a calcium chloride solution, a sodium hypochlorite solution and pure water. A tap water environment is simulated through the reagent, so that toxic substances contained in the pipe are extracted and analyzed, and the accuracy of a detection result is improved. In addition, the invention also provides a method forpreparing the detection reagent for the wading pipe. The method comprises the following steps: preparing a sodium hypochlorite solution, preparing a sodium bicarbonate solution, preparing a calcium chloride solution and preparing the detection reagent. The method is simple in process, and the prepared reagent is good in using effect. The invention further provides a detection method of the wadingpipe. The detection method comprises the following steps of pipe treatment, pipe soaking, blank test, soaking liquid collection and detection. The method is simple in process and accurate and reliablein analysis result.

Description

technical field [0001] The invention relates to the technical field of pipe detection, in particular to a detection reagent for wading pipes, a preparation method and a detection method thereof. Background technique [0002] Water-wading pipes refer to joint water-stop pipes that are in contact with drinking water during the production and supply of drinking water. Water is the source of life, the main component of the human body, and an important substance that constitutes cells, tissue fluid, plasma, etc. As wading pipes are an important material in the production and transportation of drinking water, it is particularly important to ensure the safety of wading pipes . [0003] At present, the detection data obtained by the existing detection methods for wading pipes are often not accurate enough, and it is difficult to comprehensively analyze the characteristics of the pipes. Contents of the invention [0004] The object of the present invention is to provide a detecti...
