Description

Safe and simple mercury detector

Technical Field

The utility model belongs to the technical field of the environmental protection test, especially a safe simple and easy mercury detector.

Background

Mercury pollution has become a global major environmental problem. The mercury is difficult to be discharged when entering the human body, and the mercury pollution has persistence, easy mobility, high biological accumulation and biological amplification. The situation of mercury pollution prevention is very severe, and China ranks the situation as 'twelve and five plans'.

At present, mature mercury detection technologies include a cold atomic fluorescence method, an atomic absorption method and the like, and all need large-scale instruments. Not only is expensive, but also can be operated only in a laboratory by professional personnel and cannot be monitored on site. Therefore, the development of a simple, rapid, sensitive and accurate mercury detector with self-checking function is urgently needed. Can test on site, find mercury source in time and protect environment.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the not enough of prior art, for satisfying the requirement of the mercury test of simple, quick, ability self-checking, we specially propose a safe simple and easy survey mercury ware.

The utility model discloses realize the technical scheme of purpose as follows:

the utility model provides a safe simple and easy mercury detector, be two port bottle including the main part, two port bottle upper portion system has main bottleneck, two port bottle lateral wall system has a bottleneck, coaxial inlay dress closing cap in the main bottleneck, the bottle lid is a cylindric, coaxial system of bottle lid outer fringe lower part has the binding off, the coaxial vulcanized rubber outer collar that sets up of binding off department, rubber outer collar and bottleneck department coaxial compress tightly sealedly, the middle part system has circular through-hole in the bottle lid, the coaxial system in bottle lid inner wall upper portion has the caulking groove, coaxial setting one cuprous iodide test paper disk in the caulking groove, coaxial meshing gland ring in the caulking groove on cuprous iodide test paper disk upper portion.

And a silica gel eye with the same outer diameter is coaxially embedded in the caulking groove, the inner diameter of the silica gel eye is the same as the inner diameter of the bottle cap, the outer diameter of the silica gel eye is the same as the outer diameter of the caulking groove, and the cuprous iodide test paper wafer is arranged between the silica gel eye and the gland ring.

The utility model has the advantages that:

1. the utility model provides a safe simple and easy mercury ware of surveying device structure is simple and easy, easily assembles the washing, and the low price is easily mastered in the operation, and the popularization and promotion of being convenient for has realized also can be accurate, quick, sensitive in time accomplishing the test of mercury, the on-the-spot control of being convenient for without large-scale instrument.

2. The utility model provides a safe simple and easy survey mercury ware's device leakproofness is good, does not have the leakage. The harm of the mercury vapor to operators is prevented.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.

A safe and simple mercury detector comprises a double-mouth bottle 6 as a main body, a main bottle opening 7 arranged at the upper part of the double-mouth bottle, a branch bottle opening 3 arranged on the side wall of the double-mouth bottle, a sealing cover 2 coaxially embedded in the main bottle opening, a cylindrical bottle cover, a closing-in coaxially arranged at the lower part of the outer edge of the bottle cover, a vulcanized rubber outer sleeve 4 coaxially arranged at the closing-in, a coaxial compression seal of the rubber outer sleeve and the bottle opening, a circular through hole arranged at the middle part in the bottle cover, an embedded groove coaxially arranged at the inner wall of the bottle cover, a silica gel eye ring with the same outer diameter coaxially embedded in the embedded groove, the inner diameter of the silica gel eye ring is the same as the inner diameter of the bottle cover, the outer diameter of the silica, and a gland ring 1 is coaxially engaged in the caulking groove at the upper part of the cuprous iodide test paper wafer, the cuprous iodide test paper wafer is compacted by the gland ring, and the cuprous iodide test paper wafer is arranged between the silica gel eye ring and the gland ring.

The use method of the device is as follows:

1. and (3) placing a cuprous iodide test paper wafer between the silica gel eye ring and the cover pressing ring into the main bottleneck cover for later use.

2. The mouth of the bottle is plugged with a reverse glue plug.

3. Putting the mercury-enriched mercapto-group paper wafer into a mercury detector, adding 2ml of 6mol/L HCL, covering a main bottle cap, screwing and shaking uniformly.

4. Injecting 5ml of stannous chloride solution into the test paper through a rubber plug of the branch bottle mouth by using an injector, horizontally shaking for 30min, and taking out the test paper in the main bottle mouth cover.

5. And (5) comparing with a standard card, and then measuring the content of mercury in the water sample.

6. Calculating mercury

Wherein X-the mercury content (mg) found in comparison with the standard card

0.5-volume (L) of the sample to be assayed.
