Abstract
The utility model discloses a sulfur dioxide detection reagent kit comprising a kit body, a sulfur dioxide detection reagent, a sulfur dioxide reaction tube and a sulfur dioxide detection standard color card. The kit body is made of copper plate paper. The sulfur dioxide detection reagent includes pararosaniline hydrochloride of 1.0-2.0g/L and formaldehyde of 2-4g/L. The sulfur dioxide reaction tube is a 5ml plastic microorganism tube. The sulfur dioxide detection standard color card is a color gradation used for detecting the standard color comparison of sulfur dioxide. The sulfur dioxide detection reagent kit can simplify the operation process, shorten the detection time and can finish on-site product detection within 5-10 minutes. The sulfur dioxide detection reagent kit can be broadly used for hygiene and disease control departments and supervision deparemtns and can serve as an important reference for primarily judging an event property.
Description
Technical field
The utility model relates to a kind of detection kit, specifically, relates to a kind of content of sulfur dioxide quick detection kit.Belong to the technical field that chemical analysis detects.
Background technology
Sulphite is the reduced form bleaching agent, and sodium sulphite, bisulfite, Hydros, potassium metabisulfite etc. are arranged, and is the most frequently used bleaching agent of China, and they mainly are that the reducing action of passing through the sulphuric dioxide that produced is faded the material of its effect.Sulphite is widespread use in food, as in food processing in order to make food such as preserved fruit, dry fruit.Take in the 0.2-0.5 gram and just can cause poisoning, so allow to use in the kind, except that sulphur, all stipulated the ADI value, and use and also answer simultaneously strict its sulfur dioxide residual quantity of control in control in China.
The analytical approach of sulphite in foods mainly contains hydrochloric acid Pararosaniline colourimetry and distillation direct titrimetric method at present.The former has used a large amount of noxious materials, and people, environment are all had certain harm; The latter is easy and simple to handle, but operator's subjective factor is bigger to the experimental result influence; Also have chromatography, galvanometry and chemoluminescence method in addition, these methods need expensive instrument mostly, and complicated operation, need special technician to detect, and are difficult to be applied to food, the field quick detection of environmental samples such as water sample.
The utility model content
The technical problems to be solved in the utility model provides a kind of can simplifying the operation course, and shortens detection time, and easy to carry, is fit to the kit of field quick detection sulphuric dioxide.
In order to solve the problems of the technologies described above, the utility model is achieved by following technical scheme:
A kind of sulphuric dioxide detection kit is a kind of kit of being convenient to the field quick detection content of sulfur dioxide.Described a kind of sulphuric dioxide detection kit comprises box body, sulphuric dioxide detectable, sulphuric dioxide reaction tube, sulphuric dioxide examination criteria colour atla.Described box body is a copperplate outer box made of paper.Described sulphuric dioxide detectable comprises 1.0-2.0g/L hydrochloric acid Pararosaniline and 2-4g/L formaldehyde.Described sulphuric dioxide reaction tube is a 5ml plastics bacterial classification pipe.Described sulphuric dioxide examination criteria colour atla is to be used for the color range that the standard colorimetric of content of sulfur dioxide judged in summary.
The beneficial effects of the utility model are:
(1) this detection kit is that conventional fast qualitative detects, and is at the scene sample to be carried out screening under non-breadboard condition, does not need equipment and hi-tech staffing, has avoided the waste of human and material resources.Use this detection kit to simplify the operation course greatly, shorten detection time, can in 5-10 minute, finish on-the-spot sample detection.
(2) use this detection kit can test sample in sulphuric dioxide, the sensitivity of check, stability, reliability all reach the requirement of evaluation of hygiene standard, detect to be limited to 1.0mg/kg.
(3) this detection kit can be widely used in health and epidemic prevention department, superintendent office uses.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in the figure, the utility model discloses a kind of scene that is used for and carry out the kit that content of sulfur dioxide detects.Described a kind of sulphuric dioxide detection kit comprises box body 1, sulphuric dioxide detectable 2, sulphuric dioxide detectable 3, sulphuric dioxide reaction tube 4, sulphuric dioxide examination criteria colour atla 5.Described box body 1 is a copperplate outer box made of paper.Sulphuric dioxide detectable 3 that described sulphuric dioxide detectable comprises 1.0-2.0g/L hydrochloric acid Pararosaniline--sulphuric dioxide detectable 2 and 2-4g/L formaldehyde--.Described sulphuric dioxide reaction tube 4 is a 5ml plastics bacterial classification pipe.The making of described sulphuric dioxide examination criteria colour atla 5: get 5ml plastics bacterial classification pipe number, add 0.0,5.0,10.0,20.0,30.0,40.0 respectively, 50.0mg/kg sulphuric dioxide standard solution 3.0ml, add 8 in 8 of 1.0-2.0g/L hydrochloric acid Pararosanilines and 2-4g/L formaldehyde.Room temperature was placed after 5 minutes after the jolting, made sulphuric dioxide examination criteria colour atla 5.
Inventive embodiment
Illustrate below and utilize this detection kit to carry out the step that sulphuric dioxide detects:
Embodiment 1:
Get 3ml liquid to be measured in the sulphuric dioxide reaction tube, add 8 in 8 of 1.0g/L hydrochloric acid Pararosanilines and 2g/L formaldehyde.Jolting, relatively summary is quantitative with sulphuric dioxide examination criteria colour atla after 5 minutes in the room temperature placement.
Embodiment 2:
Get 3ml liquid to be measured in the sulphuric dioxide reaction tube, add 8 in 8 of 2.0g/L hydrochloric acid Pararosanilines and 2.5g/L formaldehyde.Jolting, relatively summary is quantitative with sulphuric dioxide examination criteria colour atla after 5 minutes in the room temperature placement.
Embodiment described in the utility model is illustrative; but not it is determinate; the foregoing description just helps to understand the utility model; therefore the utility model is not limited to the embodiment described in the embodiment; every by those skilled in the art according to other embodiments that the technical solution of the utility model draws, belong to the scope of the utility model protection equally.
