Description
Technical Field
The utility model belongs to the technical field of radiation protection, and particularly relates to an aerosol filter membrane acid leaching auxiliary device.
Background
In radiation protection monitoring of places such as daily environments, nuclear power plant facilities, nuclear fuel post-treatment plants and the like, projects such as total alpha, total beta, U, sr, pu and the like or radionuclides in the air need to be monitored. During the monitoring process, aerosols in the air need to be collected and analyzed.
Typically, aerosol collection is accomplished by pumping air through a filter membrane to leave behind particles less than 100 microns in diameter. In the chemical analysis of aerosols, the prior art first cuts the aerosol filter membrane and then transfers it into a conical flask for leaching with acid to obtain the target nuclide to be measured.
In the chemical analysis flow, when the aerosol filter membrane is sheared, the collected aerosol particles are easily influenced by electrostatic effect, fly out in the shearing process, or are adsorbed on the bottle wall of the conical bottle. In addition, if the filter membrane is directly leached, the folded filter membrane is difficult to be fully immersed by leaching liquid due to the narrow mouth of the conical flask. Thus, aerosol samples are often lost due to difficulty in collecting them in their entirety, making the recovery rate monitored low and thus affecting the accuracy of the experimental results.
Disclosure of Invention
Aiming at the technical problems in the prior art, the utility model aims to provide an auxiliary device for acid leaching of an aerosol filter membrane, which can impregnate the aerosol filter membrane and avoid the loss of substances to be analyzed caused by the fact that aerosol particles fly out or aerosol samples adsorb on the wall of a bottle.
