<p><P>PROBLEM TO BE SOLVED: To provide an adsorptive material which does not react chemically with a loading agent, and can be obtained at a minimized manufacturing cost, and further, maintains a deodorizing function which is effective even to tobacco smell. <P>SOLUTION: An adsorptive material 3 can be obtained by loading an alkali 2 to a biological material 1 containing a high Ca content through loading treatment P. For the biological material 1 with a high Ca content, especially a scallop shell or other kinds of shells can be used. In addition, for the alkali 2, especially sodium hyroxide, potassium hydroxide or other kinds of strong alkali can be used. Finally, the obtained adsorptive material 3 can be used as a filter for an air cleaning unit etc. incorporated in an air cleaner or other devices. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
