Abstract
The invention discloses a kind of spectrometric instrument sample introduction pipelines by after high-content mercury pollution, and the scavenger specially of pipeline is contaminated for efficient, Rapid Cleaning.This cleaning agent is to comprise the following raw materials by weight percent：Potassium bichromate 0.05-0.20%, nitric acid 2-5%, citric acid 1-5%, surplus are water.The present invention carries out various concentration preparation using four kinds of potassium bichromate, nitric acid, citric acid, deionized water raw materials, the mercury effect eliminated in spectrometric instrument sample introduction pipeline is extremely apparent, nitric acid and citric acid in raw material can make cleaning solution remain acidic environment, cleaning solution is prevented to flow through the second adsorption for the mercury that place washes down, with the mercury in sample introduction pipeline complex reaction occurs for potassium bichromate, so that the mercury that pipeline inner wall pollutes is entered cleaning solution, achievees the purpose that clean mercury.The mercury of the cleaning solution removal sample introduction pipeline inner wall of the present invention it is very capable, to pipeline inner wall without any damage, nontoxic, free from extraneous odour, free from environmental pollution.
Description
Technical field
Sample introduction is effectively cleaned after being mercury-contaminated the invention belongs to sample introduction pipeline in analytical chemistry and spectrometric instrument work
A kind of spectrometric instrument sample introduction pipeline mercury pollution cleaning agent of pipeline, main component are potassium bichromate, citric acid, nitric acid and go
Ionized water.
Background technology
The spectral instruments such as Atomic Fluorescence Spectrometer, mercury vapourmeter, which are often used, in physics and chemistry testing laboratory carries out mercury element
It measures, the mercury element content of in general sample is all less high, will not pollute sample introduction pipeline；But in actually detected work
The higher situation of Mercury In Cosmetics content can be usually encountered, spectral instrument sample introduction pipeline is often seriously polluted, causes mercury blank
Value is very high, cannot carry out the detection work of normal mercury.The processing method of conventional elimination mercury pollution is with acid solution, hot water, heat
Acid solution etc. is rinsed as cleaning agent, but actual effect and unsatisfactory, and washing time is very long；This method is only
Can be purged the mercury of pollution to the pipeline of minuent pollution, the effective ways that processing is seriously polluted for mercury be exactly a full set replace into
Sample pipeline, it is costly and delay detection work；A kind of spectrometric instrument sample introduction pipeline mercury pollution cleaning agent of the present invention
The mercury in depollution pipeline can efficiently, be quickly removed, need to only rinse 3 to 5 times, be solved the problems, such as in 5 minutes.The present invention by
Potassium bichromate 0.05-0.20%, nitric acid 2-5%, citric acid 1-5%, remaining ingredient are constituted for deionized water.
Invention content
In order to improve detection working efficiency, the inconvenience that spectral instrument mercury pollution is brought to detection work is reduced, is saved simultaneously
Cost reduces experimenter's labor intensity and working time, keeps experimenter time saving and energy saving, and inspection work is made more to become hommization,
Invent this spectrometric instrument sample introduction pipeline mercury pollution cleaning agent.
To achieve the goals above, the present invention adopts the following technical scheme that：
