Internal circulating water purifying agent for X-ray fluorescence spectrometer, and preparation method and application of internal circulating water purifying agent

Abstract

The invention belongs to the technical field of water purifying agent preparation, and discloses an internal circulation water purifying agent for an X-ray fluorescence spectrometer, and a preparationmethod and application of the internal circulating water purifying agent; the preparation method of the internal circulation water purifying agent for the X-ray fluorescence spectrometer comprises the steps: selecting a hydrogen-type macroporous weak acid cation exchange resin and an oxyhydrogen type macroporous weak base anion exchange resin; respectively soaking the ion exchange resin with third-stage water, pouring out the soak solution, and cleaning in the third-stage water; pouring the cleaned hydrogen-type macroporous weakly-acidic cation exchange resin into the bottom of a container, filling sponge with the thickness of 5 mm in the middle for isolation, and then filling the cleaned oxyhydrogen type macroporous weak base anion exchange resin; and installing the filled device back into the instrument, and starting the instrument to operate. The prepared water purifying agent has low requirements on inflow water quality, the middle isolation cotton is added on the original basis of the container during preparation to isolate the anion exchange resin from the cation exchange resin, the purification capacity is further improved, and meanwhile, the resin is convenient to regenerate.

Description

technical field [0001] The invention belongs to the technical field of preparation of pure water agents, and in particular relates to a purifying agent for circulating water in an X-ray fluorescence spectrometer, a preparation method and an application thereof. Background technique [0002] At present, when the X-ray fluorescence spectrometer is running, most of the energy of the X-ray tube is converted into heat energy. When the light tube is running at a higher power, the target temperature can reach above 1000°C. In order to protect the light tube from being damaged at high temperatures, a cycle The water cools the target. Since the target has a high voltage of tens of thousands of volts, in order to prevent breakdown, there are strict requirements on the purity of the circulating water, and the conductivity of the circulating water must be less than 2us / cm 2 . All X-ray fluorescence spectrometers use mixed ion exchange resins to purify circulating water and reduce the ...

AI Technical Summary

Problems solved by technology

[0006] The difficulty in solving the above problems and defects is as follows: due to the mixed ion exchange resin in the X fluorescence, the adsorbed substances include silicone oil, grease, etc., which can only restore 40-60% of its original performance, and the adsorption capacity is greatly weakened; the mixed ion exchange resin of the manufacturer The exchange resin has requirements on the quality of the filled water, and it must meet the requirements before it can purify
