ABSTRACT:
Deodorant comprising 5 to 100% by weight of a calcium phosphate compound having a molar ratio of Ca/P of 0.8 to 2.0, a deodorant sheet and filter sheet containing such calcium phosphate compound, and a functional paper containing 10 to 80% by weight of a calcium phosphate compound. A filtering medium for an exhaust gas comprises a ceramic material containing 5 to 100% by weight of a calcium phosphate compound, as well as a filter cartridge and exhaust gas filter containing the filtering medium. Based on the excellent properties of the incorporated calcium phosphate compound, the agents and products according to the present invention exhibit a highly improved adsorptivity to oil-soluble substances, odor substances, animal or vegetable cells, viruses, biopolymeric substances or other substances, and therefore can be advantageously used in various fields of technology. For example, the functional paper can be used as a deodorant, filter medium and adsorbent as well as a flame-retardant paper. The filtering medium, filter cartridge and filter can be used in an exhaust system to purify an exhaust gas produced therein.
