Background technology
With the development of modern industry, environmental problem becomes increasingly conspicuous, the waste water,waste gas and industrial residue etc. in heavy industry production, such as
Fruit is discharged into waters, soil without effective processing, serious destruction can be caused to ecological environment, influences the life of the people
Life health, thus, abnormal important is become to the detection of harmful substance in environment.To the harmful substance in soil, waters such as a huge sum of money
If belonging to ion without effectively monitoring, ecological circulation can be entered with crop plant, and be eventually deposited at animal body or human body
It is interior, thus the harmful metal ion measured in soil is highly desirable, large specific surface area, the charging property of soil colloid are strong, thus
Soil has adsorptivity, and in the diffusion layer of soil colloid electric double layer, counterion can be with the ion of identical charges in solution
It is that foundation makees equal value exchange, referred to as ion exchange with ioni valence.At present in the assay method of soil harmful metal ion, exist
It is complicated pre-treatment operating process, takes longer；And manual procedure repeatedly easily causes the loss of sample, makes measurement
As a result there is the problem of deviation, mass measures the problems such as complicated, it would be highly desirable to improve.
Invention content
In order to solve the above technical problem, the present invention provides a kind of assay methods of nuisance in environmental monitoring.It can
Quickly, accurately the cation in soil is examined and determine.
The complete technical solution of the present invention includes：
A kind of assay method of nuisance, including：
Batch selects the pedotheque of area to be tested, is sent into ball mill and is ground 1-2 hours, the ratio of grinding media to material is
(10-12)：1, sample is taken out after ball milling, is weighed its quality, is calculated as M；
The above-mentioned pedotheque by ball milling is sent into dryer, is dried at a temperature of 80-90 DEG C, dries 6-8
After hour, until the moisture of pedotheque completely removes, its quality is weighed, M is calculated as0, obtain quality coefficient A=M/M0；
It is ground above-mentioned and sieve by dry pedotheque feeding Milling and screening machine, the ratio of grinding media to material is (8-10)：
1, lead to 100-120 DEG C of hot wind in mechanical milling process, ball milling takes grain size to be less than the pedotheques of 240 mesh after sieving；
The above-mentioned pedotheque through overground sieve is pressed into the square sample block that weight is 5g on cuber, is placed in modeling
It is sealed preservation in material square box；
Required above-mentioned sample blocks are taken, after being dissolved using solvent, carry out the measurement of nuisance such as heavy metal ion；It is specific to survey
Determining mode is：N times measurement is carried out, n is the integer more than 5；It takes each measured value to be calculated as P1 to Pn respectively, passes through following formula
It calculates：
Obtain the content of nuisance in soil.
The present invention is compared with the advantages of the prior art：Pass through first ball milling so that sample broke, in subsequent drying and processing,
Sample by crushing can completely remove moisture, improve drying efficiency, and grinding is again passed by after drying and is sieved so that sample
Grain size change it is tiny and uniform, convenient for dissolved in subsequent continuous mode more fully, again pass by grinding and screening process
In be passed through hot wind, prevent process water suction from measurement result being made error occur, and handled by the briquetting of batch, more easily in fact
The quick measurement for having showed batch samples avoids the cumbersome of manual weighing, and the Sample storage time is long, in the future to original measurement
When data throw doubt upon, it can still be taken out spare sample and be measured.
