METHOD FOR MANUFACTURING THE MAGNETIC MESOPOROUS SILICA, THE PROTEIN ADDUCT AND DECOMPOSITION METHOD OF AROMATIC COMPOUND USING THEREOF |
摘要 |
PURPOSE: A manufacturing method of nickel-containing magnetic mesoporous silica, a protein adduct for decomposing toxic aromatic compounds, and a decomposition method of the toxic aromatic compounds using the same are provided to rapidly immobilized histidine-based protein to the magnetic mesoporous silica. CONSTITUTION: A manufacturing method of nickel-containing magnetic mesoporous silica includes the following: mesoporous silica is stirred in a precursor aqueous solution for 2 to 3 hours to prepare precursor absorbed silica; the precursor absorbed silica is filtered, and the filtered product is stored at a temperature between -70 to -80 deg C and is vacuum-dried at the room temperature for 12 to 15 hours; silica is obtained from the vacuum-drying process and is reduced at a temperature between 400 and 800 deg C for 2 to 3 hours under the hydrogen atmosphere to prepare magnetic mesoporous silica; the magnetic mesoporous silica is arranged in a transition metal aqueous solution to be treated with ultrasound waves for 30 to 60 minutes and is stirred for 60 to 90 minutes; the stirred product is filtered, the filtered product is stored at a temperature between -70 and -80 deg C and is vacuum-dried at the room temperature for 12 to 15 hours; the vacuum-dried product is reduced a temperature between 400 and 800 deg C for 2 to 3 hours under the hydrogen atmosphere such that transition metals or transition metal ions are absorbed on the pores of the mesoporous silica.
