Abstract
The invention discloses a special cleaner used for efficiently and rapidly cleaning a contaminated pipeline after a sampling pipeline of a spectral analysis instrument is contaminated by high-content mercury. The cleaner is prepared from raw materials in percentage by weight as follows: 0.05%-0.20% of potassium dichromate, 2%-5% of nitric acid, 1%-5% of citric acid and the balance of water. The cleaner is prepared from the four raw materials including potassium dichromate, nitric acid, citric acid and deionized water in different concentrations, the effect on eliminating mercury in the sampling pipeline of the spectral analysis instrument is very remarkable, the cleaner can always keep an acidic environment by means of nitric acid and citric acid in the raw materials, secondary adsorption of mercury cleaned from places where the cleaner flows by is prevented, potassium dichromate and mercury in the sampling pipeline are subjected to a complex reaction, so that mercury contaminating the inner wall of the pipeline enters the cleaner, and the mercury cleaning purpose is achieved. The capability of the cleaner in removing mercury on the inner wall of the sampling pipeline is very high, no damage is caused to the inner wall of the pipeline, and the cleaner is non-toxic, doesn't have peculiar smell and doesn't pollute the environment.
Description
Technical field
The invention belongs to the mercury-contaminated rear a kind of spectrometric instrument sample introduction pipeline mercury pollution abluent effectively cleaning sample introduction pipeline of sample introduction pipeline in analytical chemistry and spectrometric instrument work, be mainly composed of potassium dichromate, citric acid, nitric acid and deionized water.
Background technology
Often using the spectral instrument such as atomic fluorescence spectrometer, mercury vapourmeter in physics and chemistry testing laboratory and carry out the mensuration of mercury element, in general the mercury element content of sample is all less high, will not pollute sample introduction pipeline；But in actually detected work, usually can run into the situation that Mercury In Cosmetics content is higher, often severe contamination spectral instrument sample introduction pipeline, cause hydrargyrum blank value significantly high, it is impossible to carry out the detection work of normal hydrargyrum.The conventional processing method eliminating mercury pollution is to be rinsed as abluent with acid solution, hot water, hot acid solution etc., but actual effect unsatisfactory, and washing time is very long；The pipeline that minuent is polluted can only be purged the hydrargyrum polluted by this method, and the effective ways processed for hydrargyrum severe contamination be exactly a complete set of replacing sample introduction pipeline, costly and delay detection work；A kind of spectrometric instrument sample introduction pipeline mercury pollution abluent of the present invention
Can efficiently, quickly remove the hydrargyrum in pollution pipeline, only need to rinse 3 to 5 times, in 5 minutes, solve problem.The present invention is that deionized water is constituted by potassium dichromate 0.05 0.20%, nitric acid 2 5%, citric acid 1 5%, all the other compositions.
Summary of the invention
In order to improve detection work efficiency, reduce the inconvenience that spectral instrument mercury pollution brings to detection work, save cost simultaneously, reduce experimenter's labor intensity and working time, make experimenter time saving and energy saving, make inspection work more become hommization, invent this spectrometric instrument sample introduction pipeline mercury pollution abluent.
To achieve these goals, the present invention adopts the following technical scheme that
A kind of spectrometric instrument sample introduction pipeline mercury pollution abluent, it is made up of the raw material of following percentage by weight:

Water surplus.
Wherein, described a kind of spectrometric instrument sample introduction pipeline mercury pollution abluent, its pH value should be less than 1；
The preparation method of above-mentioned spectrometric instrument sample introduction pipeline mercury pollution abluent, it comprises the following steps:
A, weighing: weigh each component according to formula；
B, spice: the potassium dichromate weighed in step a, nitric acid, citric acid and water are placed in container, stir, obtain described spectrometric instrument sample introduction pipeline mercury pollution abluent.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described.
