| titleOfInvention | Magnetic hollow silicon dioxide microballoon and its preparation technology |
| abstract | The present invention relates to a kind of preparation method that magnetic hollow silicon dioxide microballoon is prepared by template of blue-green algae.After Surface coating silica, purpose product is obtained through high-temperature process will to be permeated the blue-green algae handled well stage by stage for its technical process.The blue-green algae handled well is added to Fe by the first step 2+ Or Co 2+ Or Mn 2+ With Fe 3+ Or Co 3+ Permeated, then washed three times with distilled water in mixed salt solution；Infiltration blue-green algae after second step centrifugation, which is added in alkaline alcohol solution, permeates, and obtains the internal blue-green algae for including magnetic particle, is washed with distilled water three times, is centrifuged；Infiltration blue-green algae after the centrifugation of 3rd step carries out coated with silica, centrifugation；Product is dried after centrifuging, and high-temperature calcination removes blue-green algae template, that is, obtains magnetic hollow silicon dioxide microballoon.The present invention have the advantages that simple to operate, process be easily controlled, environmental protection and with low cost；Products obtained therefrom purity height, uniform particle diameter, magnetic response speed are fast, regular appearance, hard aggregation-free, are adapted to large-scale production, have in terms of cell separation, immobilised enzymes, Separation of Proteins and have been widely used. |
