Abstract
The utility model relates to a portable rapid determination device for arsenic in a water body. The device is characterized by mainly comprising a bottle body and a bottle cap which are in threaded connection, wherein the bottle cap consists of a gland and a cap body; the upper surface of the cap body is provided with a slot into which a test paper card is inserted; a platy pressure spring is arranged above the positioning end of the slot; and a plurality of air holes are arranged at the position of the cap body, corresponding to the inserted test paper card. The device has the benefits: the fundamental principle of the determination device is as follows: the arsenic in the water body is separated from a water sample in the form of AsH3 and reacted with the test paper card for developing. The device overcomes the problems that the original method is more complex, can not realize portability, and can carry out detection only by professionals and the like, reduces the detectable concentration of the original method on the basis, and can be used not only for the emergency accident site detection, but also for the arsenic content determination in drinking water; and the device is simple and rapid in determination.

Technical field
The utility model belongs to the environmental protection tests instrument, relates in particular to a kind of fast measuring device that satisfies arsenic in the portable water body that the water environment pollution accident emergency is handled.
Background technology
Arsenic has very strong toxicity to the human and animal, measures arsenic content in the water with arsenic spot method, and for many years this method is applied in the breadboard detection as semiquantitative method always.But the existing assay method to arsenic in the water body only limits to lab analysis, method is complicated, can not be portable, can only detect by the professional, can not be used for potable water arsenic Determination on content, more can not satisfy the needs that the water environment pollution accident emergency is handled.But along with The development in society and economy, need environmental pollution emergent accident and scene to make the fast detecting result, in order to taking necessary emergency measure.Environmental protection industry (epi) demands developing the device of arsenic in a kind of simple and easy, portable, fast measuring water body urgently, especially can be used for arsenic Determination on content in the potable water.
The utility model content
The utility model is in order to overcome deficiency of the prior art, and a kind of simple and easy, fast measuring device of arsenic in the portable water body fast is provided, and can not only be used for that emergent accident is on-the-spot to be detected, and also can be used for arsenic Determination on content in the potable water.
The utility model for achieving the above object, be achieved through the following technical solutions, the fast measuring device of arsenic in a kind of portable water body, it is characterized in that: mainly being spirally connected by bottle and bottle cap constitutes, described bottle cap is made of gland and lid, described lid upper surface is provided with the slot of grafting test card, and slot positioning end top is equipped with the sheet stage clip, and the correspondence position of described lid and grafting test card is provided with several bleeder vents.
The bottleneck end of described bottle is equipped with the filtration pipe box, and described strainer tube set upper side is uncovered, and the bottom is provided with several bleeder vents and is the filter screen shape, filters pipe box and is built-in with the anti-interference cotton of multilayer.
Described gland is connected with lid by the circlip type hinge.
Described bottle outer wall is provided with and adds the water sample mark.
Beneficial effect: this determinator ultimate principle is that arsenic in the water sample is separated with water sample with the AsH3 form, and with test paper card reaction solution.Overcome former method complicated, can not be portable, can only be by problems such as professional's detection, and reduced the concentration that detects of former method on this basis, make it to be used for the on-the-spot detection of emergent accident, also can be used for arsenic Determination on content in the potable water.Simple and easy, quick.

Embodiment
Below in conjunction with preferred embodiment, details are as follows to embodiment that foundation the utility model provides: see accompanying drawing 1-3 for details, the fast measuring device of arsenic in a kind of portable water body, mainly be spirally connected and constitute by bottle 1 and bottle cap 2, described bottle cap is made of gland 2-1 and lid 2-2, described lid upper surface is provided with the slot 4 of grafting test card 3, and slot positioning end top is equipped with sheet stage clip 5, and the correspondence position of described lid and grafting test card is provided with several bleeder vents 6.The bottleneck end of described bottle is equipped with and filters pipe box 7, and described strainer tube set upper side is uncovered, and the bottom is provided with several bleeder vents 7-1 and is the filter screen shape, filters pipe box and is built-in with multilayer anti-interference cotton 8.Described gland is connected with lid by circlip type hinge 9.Described bottle outer wall is provided with and adds water sample mark 10.
Specific operation process:
1. arsenic test card preparation
1.1 mercuric bromide test card
(1) accurately take by weighing mercuric bromide 0.350g add ethanol 100ml be made into 35% bromination mercury solution (as be difficult for dissolving can be a little heat), the solution that configures is placed brown bottle.(2) ashless quantitative filter paper is cut into 8mm * 80mm silver and places mercuric bromide solution to soak after 20 minutes, press from both sides out with the tetrafluoro rod, and erect and put dark lucifuge place, ethanol is volatilized naturally after, put in the brown bottle and keep in Dark Place.In dipping and dry run, avoid catching and touch filter paper.(3) the white plastic base of d=0.35mm～0.5mmPVC is cut into 52mm * 80mm sheet, and with its clean drying.(4) on plastic substrate, coat medical double faced adhesive tape, then the mercuric bromide bar that cuts is affixed on the substrate, and tailors slivering.
