Abstract
The utility model relates to a kit for rapidly detecting nitrite nitrogen in a water sample. The kit for rapidly detecting nitrite nitrogen in the water sample comprises a kit body, a kit cover, a needle-type quantitative pipette, a standard color chart and colorimetric test paper containing 4 aminobenzene sulfonamide and N-1naphthyl ethylenediamine hydrochloride, wherein a gasket is arranged in the kit body, a bar-type groove is arranged in the gasket; the needle-type quantitative pipette and the colorimetric test paper are respectively put into the bar-type groove; and a slot is arranged in the kit cover, and the standard color chart is inserted into the slot. The kit can detect the content range of nitrite nitrogen in aquatic water in two minutes, and the detection is rapid and convenient.
Description
One, technical field:
The utility model relates to the device for fast detecting of the nitrite nitrogen salt that contains in the surface water bodies such as crawl, reservoir, lake, what be specifically related to is a kind of kit of fast detecting water sample Nitrite Nitrogen.
Two, background technology:
In the aquaculture process, the body eutrophication phenomenon that the too high meetings of nutritive element content such as the ammonia in the water body, nitrate, nitrite, phosphate cause occurs repeatedly.Wherein the higher meeting of nitrite nitrogen toxicity causes aquatic animal and has a strong impact on, and the nitrite nitrogen conversion rate is low under the particularly pond culture condition, toxicity is large, and the Aquatic farming animals disease that causes thus increases the weight of even the dead report that frequently sees.Nitrite is that ammonia is converted into the intermediate product in the nitrate process, the one, in the middle and later periods of cultivation, the residual bait that stays owing to a large amount of bait throwing in, the a large amount of excremental accumulation of aquatic animal and the regular disinfectant that uses in the water body, harmful bacterium with useful is killed all, oxygen supply is not enough, causes the nitrous acid nitrogen nitrifying process of a large amount of accumulation to be obstructed.The 2nd because the pollution of industrial or agricultural causes content of nitrite to exceed standard, this water that is polluted, enter the pond after so that cultivation waters nitrite severe overweight.After the nitrite concentration in the water runs up to 0.1mg/L, will cause the aquatic products food rations such as fish, shrimp, crab to descend, expiratory dyspnea, move about slowly, flag, the phenomenons such as " the trip pool ", " floating head ", " stealing dead ", " emitting the end " appear in the impaired blackening of gill section.In addition, live in for a long time aquatic livestock in the higher water body of nitrite and food ration can occur and reduce, vigor is poor, immunity degradation, the easily phenomenon such as susceptible.Therefore for the raiser, be badly in need of a kind of device of content of quick, simple, cheap mensuration cultivation water nitrite nitrogen.Detect the nitrite technology in the water sample, what mainly adopt on the market at present is ultraviolet-visible spectrophotometry, but this method need to be taken back the laboratory with water sample, and the water sample that contains colourity and suspension also needs to carry out pre-service, and the time is long, and is extremely inconvenient; Also need in addition expensive instrument and equipment, common aquatic products raiser is difficult to accomplish this point.
Three, summary of the invention:
The purpose of this utility model provides a kind of kit of fast detecting water sample Nitrite Nitrogen, the kit of this a kind of fast detecting water sample Nitrite Nitrogen be used for to solve that the existing nitrite that detects water sample uses device detect inconvenient problem.
The technical scheme that its technical matters that solves the utility model adopts is: the kit of this fast detecting water sample Nitrite Nitrogen comprises box body, lid, the quantitative transfer pipet of pin type, standard color comparison card, contains the Colorimetric test paper of 4 aminobenzene sulfonamides, N-1 naphthyl ethylenediamine dihydrochloride, be provided with liner in the box body, bar-shaped trough is arranged on the liner, and the quantitative transfer pipet of pin type and Colorimetric test paper are placed into respectively in the bar-shaped trough; Be provided with slot on the lid, standard color comparison card is inserted in the slot.
After box body and lid fastened in the such scheme, box body and lid were placed in the polybag, the sealing of polybag sack.
Beneficial effect:
1, the utility model can determine the content of nitrite scope of breeding water body in 2 minutes, measured quick and convenient.
2, the utility model is simple in structure, easy to manufacture, use widely, can be most of scholar or experimenter, the environmental monitoring personnel efficiently service of providing convenience, significantly reduced their working strength, especially aquaculture family etc. does not have the personnel of experiment condition.
Four, description of drawings:
Fig. 1 is structural representation of the present utility model.
Five, embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, the kit of this fast detecting water sample Nitrite Nitrogen comprises box body 1, lid 2, the quantitative transfer pipet 6 of pin type, standard color comparison card 8, contains the Colorimetric test paper 5 of 4 aminobenzene sulfonamides, N-1 naphthyl ethylenediamine dihydrochloride, be provided with liner 3 in the box body 1, bar-shaped trough 4 is arranged on the liner 3, and the quantitative transfer pipet 6 of pin type and Colorimetric test paper 5 are placed into respectively in the bar-shaped trough 4; Be provided with slot 7 on the lid 2, standard color comparison card 8 is inserted in the slot 7.The quantitative transfer pipet 6 of pin type moves liquid measure at every turn and fixes.
In order to improve sealing, after box body 1 fastened with lid 2, box body 1 was placed in the polybag with lid 2, and the sealing of polybag sack during use, is torn polybag, and box body 1 and lid 2 are taken out.
The utility model principle of work: Colorimetric test paper 5 contains 4 aminobenzene sulfonamides, N-(1 naphthyl) chemical reagent such as ethylenediamine dihydrochloride, buffering agent, when splash into a water sample that contains nitrite nitrogen above the test paper at this, test paper will become redness, the depth and standard color comparison card 8 according to redness contrast, and just know the general concentration of water sample Nitrite Nitrogen.
During this practicality work, use the quantitative transfer pipet 6 of pin type, on standard color comparison card 8, move into respectively the equivalent pure water, move into equivalent water sample to be measured with the quantitative transfer pipet 6 of pin type toward standard color comparison card 8 equally.Consider the problem of sight equation, standard color comparison card 8 needs to splash into simultaneously water sample with Colorimetric test paper, specifically in variable concentrations series colorimetric card, splash into respectively the equivalent pure water, Colorimetric test paper then splashes into the water sample to be measured of equivalent, observe shade after 1 minute, sit in the right seat, learn the concentration of water sample Nitrite Nitrogen.
