Description
One. technical field: the utility model relates to a kind of manganese and measures utensil, particularly relates to a kind of manganese colorimetric test tube.
Two. background technology: manganese has the metallic luster of iron and steel sample, and its compound has multiple valence state, and the main valence state of manganese has divalence, trivalent, tetravalence, sexavalence and septivalency.Manganese mainly is that form with divalence, trivalent or tetravalence exists in underground water basin or the surface water.Manganese is one of biological necessary trace element, is the composition or the activator of some enzyme, participates in the generation of chondroitin sulfate in the bone matrix, and manganese prevents ataxic effect in addition, and the hematopoietic function of it and animal is closely related.But the manganese of excess intake can cause feed intake to descend, and grows and is obstructed, skeleton deformity etc., even can cause nerve dysfunction and cancer.Therefore, general industry water manganese content does not allow to surpass 0.1mg/L.The primary pollution source of manganese is the discharging of ferrous metal mine, metallurgical industry, battery industry and chemical engineering sewage.
Traditional manganese method of testing is a potassium metaperiodate oxidation photometry, and its operation steps is:
(1) 0mL is drawn in the drafting of typical curve respectively, 0.50mL, 1.00mL, 1.50mL, 2.00mL, 2.50mL the manganese standard uses liquid to place six 50mL color comparison tubes, add water to 25mL, add 10mL potassium pyrophosphate-sodium acetate buffer, add 2% potassium metaperiodate solution 3mL after shaking up again, be diluted with water to scale, shake up.Place after 10 minutes, at the 525nm place, make the reference measurement absorbance, by the absorbance of gained amount drawing standard curve behind blank correction manganese with water with the 50mm cuvette.
(2) the waste water water sample that the mensuration of sample is more with suspension or colourity is darker is got the 25mL mixing and is placed the 100mL beaker for two parts, adds 5mL nitric acid and (1+1) sulfuric acid or perchloric acid 2mL, and heating is cleared up until Mao Baiyan, is evaporated near doing, and takes off.Cold slightly back adds low amounts of water, and the low-grade fever dissolving quantitatively moves in the 50mL color comparison tube, regulate the nearly neutrality of pH value with (1+9) ammoniacal liquor, a copy of it is pressed the same steps as colour developing that typical curve is drawn, and another part replaces water sample with pure water, by same operation, measure absorbance at the 525nm place.
The problem that potassium metaperiodate oxidation photometry exists: (1) this method is to utilize potassium metaperiodate that the bivalent manganese of lower valency etc. is oxidized to the potassium permanganate of high valence state, and oxidation reaction causes result error not exclusively easily, and error is big; (2) contain the sewage of strong oxidizer or reductive agent, test is disturbed big, must measure complicated operating process again after acid is cleared up; (3) need with the Instrument measuring absorbance and with formula calculating concentration value, high to the operator quality requirement, the testing cost costliness.
Three. the utility model content:
The purpose of this utility model: simplify the manganese testing procedure, shorten minute greatly, alleviate intensity of workers, make a kind of easy to carry, manganese colorimetric test tube of using simple and fast.
Technical solutions of the utility model:
A kind of manganese colorimetric test tube is vacuum sealing tube, contains the uniform cross section glass tube of end sealing, and the opening part of glass tube is communicated with transition section with the kapillary of end sealing, and manganese determination solution is housed in glass tube, measures the height H of liquid in glass tube
1With the glass tube uniform cross section height H of leaving a blank
2Ratio be H

In glass tube, measure the height H of liquid
1With the glass tube uniform cross section height H of leaving a blank
2Ratio be H
1: H
2=1: 7～10.
Positive beneficial effect of the present utility model:
1. the utility model is with the detection technique commercialization, and commercialization is loaded on the mensuration fluid-tight for preparing in the glass tube with vacuum, can directly use.Only need during operation to fracture in the water sample to be measured capillary tube segment of test tube makes in the water sample automatic ration tail pipe to be measured and measures liquid generation metachromasia, just can draw manganese content more accurately with the contrast of standard color range behind the colour stable.Need not be when each test preparing standard solution, reagent, can simplify the detection step greatly, save minute, reduce workload, reduce labor intensity.
2. it is reasonable that the utility model is measured formula of liquid, advanced technology, and stable performance is used simple.Adopt standard sample liquid to react with it in advance, constant color forms permanent colour code standard, and encapsulation forms the contrast color range, carries out the scene and detects, and need not to prepare other any reagent, and testing result accurately and reliably.The standard colour code can be made by standard color range pipe of the present utility model and form, and also by the computer color atlas, or the colored printing cardboard, or the colored plastic rod, or other physical medium material such as stained glass goods forms, and uses very convenient.
3. the utility model method of testing is compared with changing photometry, has obviously reduced measuring process, has accelerated finding speed.
4. to measure the chromogenic reaction of liquid and determinand manganese be to carry out automatically under given conditions the glass tube with vacuum to the utility model, can effectively avoid accidental error and personal error, testing result meets the requirement of water analysis error precision accurately and reliably, and detection limit meets national sewage comprehensive emission standard.
The utility model carry, easy to use, measure simple fast, accurately, the holding time is long.The on-the-spot detection do not need the miscellaneous equipment instrument, saves human and material resources greatly, reduces integrated cost.The utility model is easy to promotion and implementation, has good social and economic benefit.
