Abstract

The invention discloses a chlorinated phenol detection reagent and a preparation method thereof, which belong to the technical field of chemical detection. The detection reagent comprises the following components in parts by mass: 5-12 parts of tributyl phosphate, 6-18 parts of 4-amino-antipyrine, 2-5 parts of sodium thiosulfate, 1-3 parts of sodium hydroxide, 1-3 parts of palladium chloride, 2-6 parts of sodium carbonate, 2-7 parts of zinc sulfate, 6-12 parts of ethyl alcohol and 12-25 parts of deionized water. The chlorinated phenol detection reagent has the characteristics of being efficient, quick and visual, is relatively high in sensitivity, relatively simple to operate and relatively low in cost. The chlorinated phenol detection reagent is used as an ideal chlorinated phenol detection reagent.

Description

Technical field [0001] The invention is a chemical testing technology field, which specializes in a chloride phenol test reagent and its preparation methods. Background technique [0002] Phenol is a typical representative of organic pollutants in the water. It is easy to react with many sodium chloride disinfectants including sodium hypochlorite. During the reaction process, a series of intermediate products will be generated, and then gradually oxidized into small molecular compounds. [0003] These phenols and its chloride have great damage to the human body. Long -term contact or stimulation can cause damage to human organs. Therefore, phenol and its chloride are also one of the important indicators of water quality detection. [0004] The analysis methods of phenols and its intermediate products are mainly gas color spectrum and high -efficiency liquid chromatography. Among them, the HPLC method does not require tedious derivatives, and has good selectivity, reproduction and...
