Description
Technical field
The utility model relates to heavy metal analysis technical field, especially relates to a kind of paper box for detecting contents of many kinds of heavy metal ion fast.
Background technology
Heavy metal is one of important environmental contaminants of a class, can enrichment in vivo, and enters human body by channels such as air, potable water and foods, causes comprise carcinogenic, teratogenesis and mutagenesis etc. serious harm to health.Therefore, the detection of heavy metal, especially one of the quick detection focus becoming public attention of heavy-metal residual in agricultural product, food, potable water.
Traditional heavy metal detection method mainly contains atomic absorption spectrography (AAS), atomic emission spectrometry, atomic fluorescence spectrometry, anodic stripping voltammetry, chromatography of ions, spectrophotometric method etc., but all there is expensive equipment in major part, consuming time, operating cost is high, need the shortcomings such as professional operates, be difficult to the actual needs meeting field quick detection, be thus usually applied to all kinds of test in laboratory.Along with people are to the reinforcement of Consciousness of food security, those free of contamination green health food more and more welcomed by the peoples.Market is badly in need of a large amount of sxemiquantitative method for quick even qualitatively, sample does not generally need the pre-treatment through complexity, only need a few minutes just can go out testing result by more than ten minutes, which kind of scope the content whether containing a certain amount of object or object in preliminary judgement sample is roughly in.
The quick detection kit of current heavy metal ion on the market, normally liquid reagent, also test paper form is had, such as, the Chinese patent of Authorization Notice No. CN102776266B, authorized announcement date 2015.3.18 discloses a kind of heavy metal Hg rapid detection card, and this test card structure is followed successively by from the bottom to top: base plate, adsorbent sheet, epiphragma, described base plate is fixed with respectively the thin slice of the thin slice of at least one absorption developer, at least one absorption urase, thin slice does not overlap each other.The weak point of this test card is, enzyme, substrate and developer are separately fixed on two thin slices, need fluid drips during use on a thin slice, doubling makes thin slice 2 and thin slice 3 be stacked and contact with each other again, and pinches and do not put certain hour, then could develop the color, not only use very inconvenient, detection efficiency is low, and can not ensure that two thin slices can fully contact, and develops the color uneven and testing result error is larger.
Utility model content
The utility model is that the detection of heavy metal ion kit in order to solve prior art uses very inconvenient, detection efficiency is low, develop the color the uneven and problem that testing result error is larger, provide a kind of structure simple, use with easy to carry, colour developing rapidly, evenly, detection efficiency is high, and testing result is accurately for detecting the paper box of contents of many kinds of heavy metal ion fast.
To achieve these goals, the utility model is by the following technical solutions:
A kind of paper box for detecting contents of many kinds of heavy metal ion fast, comprise housing and the gland suitable with housing, described housing is the rectangular structure of open top, bottom surface in described housing is provided with non-drying glue layer, the surface of described non-drying glue layer is provided with water suction bar along its length relatively, described water suction bar and inner walls are fitted, non-drying glue layer between water suction bar is provided with the colour developing absorbent filter being fixed with urea and cresol red from the bottom up successively, water-soluble barrier paper and be fixed with the cellulose acetate membrane of urase, described gland water white transparency, gland is provided with sample liquid inlet hole, the bottom of described gland is provided with drainage trough along gland length direction, described drainage trough is positioned at sample liquid inlet hole both sides and is connected with sample liquid inlet hole, gland be crimped on be fixed with urase cellulose acetate membrane surface and connect and fix with housing.Principle of the present utility model quantitatively detects heavy metal ion content in sample by urea inhibiting AChE, and the shell in the utility model can avoid the utility model that bending damage occurs, and is easy to carry and preservation, non-drying glue layer plays the effect of sizing, avoids colour developing absorbent filter generation fold thus affects color developing effect, water-soluble barrier paper is meet the ply of paper that the organic polymer that namely dissolves of water makes, effectively can prevent the urase in cellulose acetate membrane and the substrate contact in colored filter paper when not using and enzymatic reaction occurs, thus the false negative rate effectively reduced when using, when deployed, when moisture is immersed in this layer, water-soluble barrier paper dissolves, substrate reactions on urase in cellulose acetate membrane and colored filter paper layer, pH is raised, thus makes indicator discoloration, the colour developing of colour developing absorbent filter, gland water white transparency, can directly observe, very convenient, the bottom of gland is provided with drainage trough along gland length direction, drainage trough is positioned at sample liquid inlet hole both sides and is connected with sample liquid inlet hole, detection sample liquid in such sample liquid inlet hole is just rapidly to the both sides diffusion of sample liquid inlet hole under the sucking action of water suction bar along drainage trough, thus make the detection sample liquid in sample liquid inlet hole infiltrate in cellulose acetate membrane rapidly and fully, not only can avoid detecting sample liquid and save bit by bit impact infiltration in sample liquid inlet hole, greatly shorten the response time of enzymatic reaction, and colour developing is more rapid, develop the color also more even, raising detection accuracy is also helped while raising detection efficiency.
As preferably, be provided with and can take off waterproof paper outside described sample drop hand-hole.Waterproof paper can be taken off play a protective role, outside moisture effectively can be stoped to contact with cellulose acetate membrane thus cause cellulose acetate membrane to lose efficacy, during use, opening and can take off waterproof paper.
As preferably, the end face of described gland surfaces and housing flushes.
As preferably, the upper end end face of described water suction bar and the surface of cellulose acetate membrane flush.
As preferably, the end at described gland two ends is outwardly is formed with protuberance, and described inner walls is provided with the draw-in groove suitable with protuberance, and described gland and housing coordinate clamping by protuberance and draw-in groove.
Therefore, the utility model has following beneficial effect:
(1) surface of non-drying glue layer is provided with water suction bar along its length relatively, the bottom of gland is provided with drainage trough along gland length direction, drainage trough is positioned at sample liquid inlet hole both sides and is connected with sample liquid inlet hole, detection sample liquid in sample liquid inlet hole can be rapidly to the both sides diffusion of sample liquid inlet hole under the sucking action of water suction bar along drainage trough, thus make the detection sample liquid in sample liquid inlet hole infiltrate in cellulose acetate membrane rapidly and fully, not only can avoid detecting sample liquid and save bit by bit impact infiltration in sample liquid inlet hole, greatly shorten the response time of enzymatic reaction, develop the color more rapid, and colour developing is also more even, raising detection accuracy is also helped while raising detection efficiency,
(2) structure is simple, is easy to preserve and carry, and very easy to use.
Accompanying drawing explanation
Fig. 1 is a kind of vertical view of the present utility model.
Fig. 2 is a kind of longitudinal sectional view of Fig. 1 along A-A direction.
