| titleOfInvention | Method for preparing titanosilicate using dropwise method and titanosilicate absorbent for removing radioactive nuclides prepared thereby |
| abstract | The present invention relates to a method for preparing titanosilicate using a dropping process, which comprises the steps of: (a) mixing a titanium precursor with a silicon precursor to provide a first mixed solution; (b) mixing sodium hydroxide with distilled water to provide a second mixed solution; (c) supplying the first mixed solution to a reaction container and agitating it under a constant speed, and then supplying the second mixed solution to the first mixed solution through a dropping process to provide a third mixed solution; and (d) heating the third mixed solution to obtain crystallized titanosilicate. The method for preparing titanosilicate using a dropping process according to the present invention utilizes a hydrothermal reactor including a large-capacity teflon container and a feed container capable of controlling a flow rate to agitate the mixed solution containing the titanium precursor mixed with the silicon precursor strongly with an agitator, while an aqueous sodium hydroxide solution is supplied evenly in a uniform amount through a dropping process so that it may be mixed and agitated with the mixed solution. Thus, it is possible to maintain a reaction molar ratio constantly without solidification including agglomeration of the reaction solution and to allow an optimized condition of the reaction for synthesis to be maintained continuously. Therefore, it is possible to carry out mass production of titanosilicate efficiently. |
