Abstract

The invention provides a preparation method of a nanometer single substance tellurium hydrosol coupled with sucrose molecules, which has the following steps: homogeneous water solution is formed by mixing the sucrose and tellurite, and the hydrosol consisting of the sucrose molecules and the nanometer single substance tellurium can be obtained after the reaction of the water solution under the condition of hydro-thermal reactions or high pressure steam sterilization. The products prepared by the invention only contain the sucrose and the nanometer single substance tellurium without any additives, and the products are preserved by the hydrosol form, thus expanding the application range of the nanometer single substance tellurium; the invention is simple and easy in application, low in reaction temperature and short in time and can be synthesized by one step; and no template agent needs to be added in the preparation process, thus eliminating adverse effects of the template agent possibly caused in real applications. The invention has the advantages of low production cost and the like, and not only is convenient for small batches of experiments in labs, but also is beneficial to scaled industrialized productions; and one of the preparation processes provided by the invention is the high pressure steam sterilization which can solve the problem of microorganism pollution and is beneficial to the storage and application of products.

Description

technical field [0001] The invention relates to a preparation method of nano element tellurium hydrosol coupled with sucrose molecules, and belongs to the technical field of nano material preparation. Background technique [0002] Tellurium is generally considered to be a toxic element that is toxic to most organisms, but recent studies have shown that certain organotellurium compounds have anti-lipid peroxidation, anti-tumor activities, etc. Since tellurium is in the same family as selenium and has similar properties, some people speculate that tellurium and selenium may have similar or similar biological functions in living organisms. [0003] In recent years, the biological activity of red nano-selenium and its application in the field of life sciences have become an international research hotspot, and the related research on nano-tellurium has also begun to attract attention. The preparation method of nano-selenium or nano-tellurium usually adopts a reduction method to ...
