Abstract
The invention provides the chemical analysis method of such as lead, cadmium, copper, cobalt, chromium, the nickel equal size of heavy metal ion in a kind of water, including take different volumes sample, calculate volume factor, concentrate, obtain enrichment factor, using atomic absorption spectrography (AAS), plasma mass spectrometry, fluorescence method, AAS, chemoluminescence method etc. analyze examine and determine, and the step of calculate content, the present invention is applied widely, error can be effectively reduced, analysis precision is improved.
Description
Technical field
The invention belongs to environmental monitoring or chemical analysis technology field, and in particular to the chemistry of heavy metal ion content point in a kind of water
Analysis method.
Background technology
With the propulsion of process of industrialization, the manufacturing industry of China is developed rapidly, but the industrialization development of China is also in just
Level stage, the production of suitable multiple enterprises belongs to extensive and heavily contaminated type, and furthermore the technology of environmental protection and Supervision Measures is not in place,
Some industrial and mineral polluted enterprises are in order to reduce cost, and seeking results often not pass through the waste material produced in production process and sewage
Cross effectively processing and be directly discharged in river, lake, reservoir, cause heavy metal contaminants in above-mentioned waters and persistently organic
Pollutant severe overweight, ecological environment is seriously damaged, therefore, and the heavy metal ion in environment waters is accurately detected,
It is significant so as to realize effective monitoring and the processing for next step provides support, but be due to the metal ion in waters
Content is complicated, and detection process noise is big, and detection is complicated, and the error of generation is easily exaggerated, so that testing result distortion.
The content of the invention
In order to solve the above-mentioned technical problem, can the invention provides a kind of chemical analysis method of heavy metal ion content in water
Effectively reduction error, improves analysis precision.
The complete technical scheme of the present invention includes：
The chemical analysis method of heavy metal ion content, comprises the following steps in a kind of water：
(1) same target water is directed to, prepares n parts of samples, described sample volume is calculated as A respectively1, A2, A3... ... An,
N is the positive integer more than 3；
(2) the above-mentioned coefficient B of n parts of sample first is calculated respectivelyi, whereinWherein i=1,2,3 ... ... n；
(3) above-mentioned n parts of sample is concentrated respectively, the volume after every part of sample concentration is calculated as Ci, and respectively obtain each part
Second coefficient of sample
(4) analysis calibrating is carried out respectively to above-mentioned n parts of sample, the content of each part sample is calculated as Ei；
(5) obtaining content isWherein H is correction factor, and H values are 0.97=1.14.
Described heavy metal ion is the one or more in lead, cadmium, copper, cobalt, chromium, nickel.
In step (4) sample carry out respectively analyze calibrating method for atomic absorption spectrography (AAS), plasma mass spectrometry, fluorescence method,
One kind in AAS, chemoluminescence method.
The present invention compared with the prior art, using the multiple sample of different volumes, and by being detected after concentration, improves analysis precision,
By detection level multiple averaging, the analytical error of sample is effectively prevent, precision is improved.
