Abstract
The present invention discloses a preparation method of a drinking water residual chlorine detection reagent which includes the following components by weight: 5.5% to 8.5% of phenylenediamine; 3.2% to 5.3% of triethylamine hydrochloride; 0.5% to 1.7% of manganese dioxide; 1.5% to 3.5% of hydrogen peroxide; 15.5% to 28.5% of nitric acid; and balance of deionized water. Through use of certain content of the phenylenediamine, the drinking water residual chlorine detection reagent is more sensitive, by use of the triethylamine hydrochloride as a catalyst of the drinking water residual chlorine detection reagent, the reagent is faster in test speed, the drinking water residual chlorine detection reagent has the characteristics of being low in price, easy to carry, and the like, and non-professionals can operate.
Description
Technical field
The present invention relates to the preparation method that a kind of Remanent Chloride In Drinking Water detects reagent.
Background technology
Along with the fast development of industrial technology, Sudden Pollution Accident constantly increases, and threatens human health, saboteur's ecologic environment, seriously governs the ecologic equilibrium and society, expanding economy.Take precautions against abrupt polluting accident problem demanding prompt solution a lot, top priority sets up monitoring method for emergency technology, once contamination accident occurs, can drop into monitoring rapidly, contamination data is accurately provided, for antipollution diffusion and take counter-measure to provide scientific basis within the shortest time.Therefore, extremely strong for Time and place characteristic, the significant Sudden Pollution Accident of random variation, Site Detection obtain in time and the accurate perfect answer of answer comparatively accurately comes too late than one test in laboratory is valuable many.In-situ check and test method normally detects in real time in workplace, namely records in sample whether there is test substance and concentration thereof at short notice.It is few that method for Site Detection needs sampling quantity, and possess higher accuracy and sensitivity, the feature such as the instrument fast, to use easy and simple to handle is easy to carry.In-situ check and test method comparatively ripe at present has test paper method, detects tube method, miniature LHD units, Bioexperiment method, portable instrument method etc.Water quality chlorine residue detection method mainly contains photometry, Using Flow Injection Analysis, the chromatography of ions, polarography etc., the most complex operation of these methods, tediously long time-consuming, has higher requirement, often can only perform in laboratory the professional skill of operating personnel.
Summary of the invention
The defect that the present invention seeks to exist for prior art provides a kind of Remanent Chloride In Drinking Water to detect the preparation method of reagent.
The present invention for achieving the above object, adopt following technical scheme: a kind of Remanent Chloride In Drinking Water detects the preparation method of reagent, comprise the steps: to get the phenylenediamine that percentage by weight is 5.5% ~ 8.5%, percentage by weight is the triethylamine hydrochloride of 3.2% ~ 5.3%, percentage by weight is the manganese dioxide of 0.5% ~ 1.7%, percentage by weight is the hydrogen peroxide of 1.5% ~ 3.5%, put into ultrasonic grinder successively fully to mix, incorporation time is 20 ~ 30 minutes, then the nitric acid being 15.5% ~ 28.5% by mixed raw material and percentage by weight joins in reactor and fully reacts, reaction time is 20 ~ 30 minutes, temperature of reaction is 40 ~ 50 degree, then suitable deionized water is added, and fully stir, mixing, finally obtained required chlorine residue detects reagent.
Beneficial effect of the present invention: chlorine residue of the present invention detects the phenylenediamine adopting certain content in reagent, the sensitivity that reagent is detected is higher, adopt triethylamine hydrochloride as the catalyzer of reagent, make reagent test speed faster, have the features such as cheap, easy to carry, layman can operate.
