Description
Technical field
This utility model is related to a kind of test pen of mercury ion in quick detection domestic water；Belong to water quality detection equipment to open
Send out technical field.
Background technology
Heavy metal Hg is distributed widely in nature, the exploitation produced with the fast development of Chinese society economy, mercury ore
Developed rapidly, yield and mineral products demand rapid growth, be that Chinese society expanding economy is made that huge contribution.
But, also result in serious environmental pollution, according to statistics, national 27 trunk rivers, great majority are heavily polluted, and hydrargyrum generally surpasses
Mark several times to tens times, the exceeding standard rate of immediate offshore area sea water hydrargyrum reaches 62.9%[1]；The whole nation about 1/5 arable land is subject to heavy metal pollution[2],
Part heavy metal pollution of soil causes food-safety problem.Environment in recent years heavy metal pollution event frequently occurs, only 2009
Chinese Ministry of Environmental Protection is informed of a case the contamination accident of 12, Shaanxi Fengxiang etc. altogether.These events cause that 4035 human blood hydrargyrum are exceeded, 182 people's cadmiums are exceeded,
Cause 32 Mass disturbances.The environmental pollution of heavy metal seriously compromises the health and safety of the mankind.
World Health Organization (WHO) in water hydrargyrum be controlled to 0.01mg/L, in China's Drinking Water the content of hydrargyrum for
0.01mg/L.
The main method that mercury ion measures has traditional colorimetry ultraviolet one visible spectrophotometry, Atomic Absorption and atom
Emission spectrometry, atomic fluorescence spectrometry etc..This kind of method has the advantages that sensitivity height, accuracy are good, but usually needs to borrow
Help some analytical tool costly, generally require and be analyzed measuring by professional in specialized laboratory, complex operation,
Relatively costly it is difficult to meet the needs of rapid screening.In substantial amounts of real work, particularly some daily life water are supervised
In the work such as control, emergency management, usually do not need accurate quantitative result, and only need to the limit value specifying according to standard
Judge " qualified " or " unqualified ".Now, the quickly cheap qualitative semiquantitative determination method in scene is more practical, only right
The sample that those are in critical point just needs to be analyzed measuring with the instrument analytical method of accurate quantitative analysis further.Therefore, real
In existing Drinking Water solution example, the rapid field detection of mercury ion, has in the field such as environmental conservation and monitoring and preferably should
With being worth.
Current water quality test pencil mainly includes a body, circuit board and control panel, and circuit board is arranged in a body, circuit
Plate is provided with display screen and button switch, and the corresponding display screen of a body and button switch are provided with perforate, and perforate is posted with labelling
Film so that as control panel, wherein, film is fixed by one side glue or double faced adhesive tape, the wherein fixing feel of one side glue is poor, as
The sensation double faced adhesive tape of the product of inferior quality fixing in life-time service or poor environment such as hot and humid use, easily occur sticking up
Rise, the bonding bad phenomenon such as loosely so that product failure.
