Abstract

The invention provides a production method of low-radioactive negative ion nanomaterials, adding rare earth materials into an acid solution to dissolve, and obtaining a filter residue and a filtrate after filtration; adding soluble sulfate solution to the a filtrate for reaction, and filtering to remove b filter residue after the reaction , to obtain b filtrate; add soluble carbonate solution to b filtrate for reaction, filter and remove c filtrate after reaction to obtain c filter residue; mix a filter residue and c filter residue and grind them into a powder of 5-10 μm fine particles; Add water and ethylene glycol to make a suspension; add penetrant, stabilizer, and coupling agent to the suspension to obtain auxiliary agents, centrifuge the aid, and pour out the centrifuged liquid to obtain the finished product. The present invention removes the radioactive nuclides radium-226, thorium-232, and potassium-40 in negative ion materials, and obtains a stable dispersion liquid of nano-level negative ions through micro-processing, which solves the radioactive problem of negative ion nanomaterials and makes it suitable for use Avoid safety issues when using textiles.

Description

technical field [0001] The invention relates to the technical field of negative ion nanomaterials, in particular to a method for producing low-radioactive negative ion nanomaterials. Background technique [0002] Nowadays, the anion nanomaterials used in textile fabrics are mostly directly processed with rare earth materials to remove impurities, ignoring the hazards of radionuclides radium-226, thorium-232, and potassium-40 in the anion raw materials, resulting in the addition of The textile radioactivity of negative ion nanomaterials seriously exceeds the standard, causing product safety problems. The invention aims to solve the radioactivity problem of the negative ion nanometer material, and deeply extracts the radioactive nuclide in the material. Contents of the invention [0003] Purpose of the invention: the purpose of the present invention is to provide a kind of production method of low-radioactive negative ion nano material for the deficiencies in the prior art....
