Technical field
The utility model relates to a kind of chemical analysis experiment device, particularly a kind of indirect iodometric processes titration apparatus.
Background technology
Indirect iodometric processes is a kind of conventional chemical analysis titration method.Utilize iodide ion and oxidant reaction to generate elemental iodine under certain condition, then with the elemental iodine that the titration of sodium thiosulfate standard titration solution generates, thus according to the amount that sodium thiosulfate standard titration solution consumes, just can the content of indirect determination oxidizing substance.Indirect iodometric processes is widely used in fields such as metallurgy, chemical industry, pharmacy and food.
But owing to there being the generation of elemental iodine in course of reaction, in the titrimetric process of employing indirect iodometric processes, often require that reaction is carried out in iodine flask, under lucifuge condition, its object is to prevent the volatilization of elemental iodine and avoid light to impact reaction.So usually when carrying out this type of experiment, iodine flask can only be placed on dark place certain hour by operating personnel, but this does not meet the condition of lucifuge, and in the dark carries out titration and also there is inconvenience.Although use iodine flask in addition, in titration process, bottle cap cannot cover, and iodine flask performs practically no function substantially, and elemental iodine volatilizees away very soon in mensuration process, causes measurement result accurately impossible.
Therefore can either meet a lucifuge requirement for indirect iodometric processes, the indirect iodometric processes titration apparatus that can prevent again elemental iodine from volatilizing becomes the key of dealing with problems.
Utility model content
The purpose of this utility model is to provide one can either meet lucifuge requirement, can prevent again the indirect iodometric processes titration apparatus that elemental iodine volatilizees.
For achieving the above object, the utility model adopts following technical scheme:
A kind of indirect iodometric processes titration apparatus, comprises bottle, is provided with interlayer on bottle top, and interlayer upwards extends and is connected with bottleneck, and between bottleneck top and interlayer, a formation annular space, interlayer is provided with multiple aperture; Be provided with an opening at the upper wall of bottle, opening is connected with the annular space of formation, and one end of sebific duct is connected with opening; At the bottle mouth position of bottle, be provided with the plug matched with bottleneck, plug is provided with two through holes, buret and separating funnel stretch in bottle respectively by through hole; Be provided with magnetic stirring apparatus in the lower end of bottle, the rotor of magnetic stirring apparatus is positioned at bottle; Be provided with light shield in bottle outside, the position of light shield upper end corresponding sebific duct, buret and separating funnel is provided with hole, and sebific duct, buret and separating funnel can be supplied to pass.
As preferred further, on described plug, through hole matches with buret and separating funnel respectively.
As preferred further, the hole on described light shield matches respectively at sebific duct, buret and separating funnel.
As further preferably, be respectively equipped with transparent part for front sight and rear view window at the front and back of described light shield.
As preferred further, the height of described transparent part for front sight and rear view window is 1/2nd places to bottle volume from bottle body bottom, and width equals bottle diameter.
As further preferably, the white plaque that form place outer lining one piece and rear view window etc. are large in the rear.
As further preferably, described sebific duct is provided with tongs.
As preferred further, the inside surface of described light shield is the lucifuge material be made up of aluminum foil film.
The beneficial effects of the utility model are: the requirement both having met indirect iodometric processes lucifuge turn avoid the volatilization of elemental iodine, ensure that the accuracy of test; Whole apparatus structure is simple, easy to operate, have very strong practicality.
