Description
Technical field
The present invention relates to agriculture test Instrument technology field, in particular to a kind of heavy metal-polluted soil characterization processes.
Background technique
With heavy metal than more prominent in soil inorganic pollutant, mainly since heavy metal cannot be by edaphon point
Solution, and is easy to accumulate, and is converted into the bigger methyl compound of toxicity, in addition some by food chain with adverse concentration in human body
Accumulation seriously endangers human health.Heavy Metals in Soil Contaminated element mainly has mercury, cadmium, lead, copper, chromium, nickel, zinc etc..
Present heavy metal-polluted soil detection device is less accurate to the detection of heavy metal, especially the soil of field depths
It can not be detected with detection device, the soil of depths is merely able to detect by the method for chemical detection.
Existing patent also proposed the detection method of heavy metal-polluted soil, and application No. is 201610135192.6 Chinese inventions
Patent discloses a kind of detection method of heavy metal in soil, which pre-processes sample using alkaline hydrolysis acid formulation, keeps away
Exempted from the loss and air pollution of heavy metal element, at the same have the rate of recovery is good, precision is high, processing speed is fast, it is easy to operate,
The advantages that being applicable in wide model, although which is able to carry out the detection of heavy metal-polluted soil, but soil does not pass through " winged silicon " processing,
Heavy metal-polluted soil detection is caused to have deviation；Application No. is 201820277615.2 Chinese utility model patents to disclose one kind just
Prompt formula heavy metal-polluted soil fast detector, the weight for carrying out soil using the novel height by adjusting detection probe and position
Metal detection can not detect the content of beary metal inside soil.
Existing particular problem is as follows when in existing heavy metal-polluted soil detection to soil progress acid processing, can not be for difference
The crucible of model carries out holding action, so that crucible clamp needs are replaced according to various sizes of crucible, it is artificial right to need
Crucible is shaken, and be easy to cause the problems such as mixture is trickled down, causes detection effect poor in crucible, people when artificial crucible shaking
Work is stirred the splashing that corrosive liquids is be easy to cause when movement to crucible, causes security risk to personnel.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of heavy metal-polluted soil characterization processes, it can solve existing soil
It is existing when carrying out acid processing to soil in heavy metal analysis to carry out holding action for the crucible of different model, need people
It is easy to cause in crucible that mixture is unrestrained, when being manually stirred movement to crucible when work shakes crucible, crucible shakes
The problems such as be easy to causeing security risk may be implemented that the crucible for containing soil is clamped and shaken when soil carries out acid processing
Function dynamic, that it is stirred when crucible is heated, have can be carried out for the crucible of different model holding action,
It not will cause that mixture in crucible is unrestrained, mechanization is stirred crucible when mechanization shakes crucible, crucible shakes
The advantages that movement is without security risk.
To achieve the goals above, the present invention use following technical scheme, a kind of heavy metal-polluted soil characterization processes, including with
Lower step:
