Abstract
The utility model discloses a device used for rapidly detecting sulphate in water. The device comprises a transparent plastic detection tube, the two ends of which are closed. The device is characterized in that an active reagent layer containing barium chromate and silica gel is arranged at the middle part of the transparent plastic detection tube; and water conductivity layers made of water conductivity materials are arranged at the two ends of the active reagent layer. The device is simple and convenient to use without adding any extra reagents, and only needs to be compared with a scale in a specification after the reaction is ended so as to obtain a detection result. Changes before and after the reaction are straightforward by using the transparent plastic detection tube. The device is suitable for measuring the concentration of sulphate in water in the field.
Description
Technical field
The utility model relates to a kind of pick-up unit, particularly a kind of device that is used for fast detecting water sulfate.
Background technology
The method that existing turbidimetry detects sulfate in the water is: water sampling at first, water sample is put into cuvette, will be placed on the reaction reagent of preserving in the aluminium foil bag again and add in the cuvette, after question response is finished, cuvette is placed on the tintmeter measures, to obtain testing result.The essential tintmeter of above-mentioned detection method, operation steps is more loaded down with trivial details.When testing, carry the tintmeter inconvenience in the open air.All the other methods that detect sulfate in the water also have gravimetric method, spectrophotometric method, the chromatography of ions etc., need exact instrument such as spectrophotometer, precision balance, ion chromatograph, and operation steps is more loaded down with trivial details.When testing, carry the instrument inconvenience in the open air.
Summary of the invention
The utility model provides a kind of easy to use, device that is used for fast detecting water sulfate of being convenient for carrying for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: a kind of device that is used for fast detecting water sulfate, the transparent plastic detector tube that comprises closed at both ends, be provided with the active reagent layer that is made of barium chromate and silica gel at the middle part of described transparent plastic detector tube, the two ends of described active reagent layer are provided with the water guide layer that is made of the water guide material.
The internal diameter of described transparent plastic detector tube is 1-10mm.
The thickness of described active reagent layer is 5-10cm.
The thickness of described water guide layer is 1-2cm.
Advantage and the good effect that the utlity model has are: easy to use, do not need to add in addition any reagent, reaction finish that the back only needs and instructions in scale compare, can obtain testing result.Use lucite pipe, the variation before and after the reaction comes into plain view.Be adapted at the sulfate concentration in the field condition measurement water.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, transparent plastic detector tube, 2, cavity, 3, the water guide layer, 4, active reagent layer.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of device that is used for fast detecting water sulfate of the utility model is provided with the active reagent layer 4 that is made of barium chromate and silica gel in the transparent plastic detector tube 1 of closed at both ends.According to the needs that sulfate in the water detects, the thickness of active reagent layer 4 is 5-10cm.The internal diameter of lucite pipe 1 is 1-10mm.Be provided with the water guide layer of being made by absorbent material 3 at active reagent layer 4 two ends, water guide layer 3 has the effect that water is imported detector tube when reaction, and the effect that stops reaction reagent to leak from detector tube is also arranged simultaneously.Water guide layer 3 not only can improve detection speed, can also stop suspended contamination.The thickness of water guide layer is 1-2cm.Cut the enclosure portion of lucite pipe for convenience, be provided with one section cavity 2 between water guide layer and the blind end.
Transparent plastic detector tube two ends seal secluding air at ordinary times.When measuring, cut off the plastic tube two ends, expose the water guide layer, vertically be placed in the water sample, water is under capillary action, automatically the end by active reagent layer soaks into to the other end, the reaction reagent barium chromate is presenting the change color that naked eyes can obviously be distinguished with sulfate reaction front and back, by the light yellow white that becomes, the concentration of sulfate has determined detector tube by the pale yellow variable color length that becomes white in the water, with the scale in variable color length and the instructions relatively, by measuring reaction back detector tube by the pale yellow variable color length that becomes white, get final product the concentration of sulfate in the water outlet.
Use example of the present utility model:
Choosing internal diameter is 2mm, and length is one of the transparent hollow plastic tube of 8cm, with an end heat fused of detector tube, makes mouth of pipe sealing, puts into the water guide layer in the port.The active reagent layer of packing into is put into the water guide layer, with an end hot melt of opening, with mouth of pipe sealing, makes above-mentioned detection device again.
With water sample cup water sampling 50ml, the cavity part two ends of above-mentioned detection device are cut off, the real detector tube silica gel of pier, an end inserts in the water sample downward vertically, water sample slowly sucks, by the water guide layer, soak silica gel in the pipe, wait and soak to Guan Dinghou 1 minute, take out pick-up unit, observe the pale yellow variable color length that becomes white, compare quantitatively, try to achieve sulphates content in the water sample with sulfate standard quantitative chi.
Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
