摘要： A water purifying material which is used for treating water for domestic and industrial uses and comprises activated carbon and zeolite containing silver combined therewith or a zirconium phosphate compound containing silver supported thereon. The material has an excellent antibacterial activity, a high rate of operation, and an improved function of adsorbing and removing various factors detrimental to the taste of water, such as limy odor due to free chlorine, impurities, malodorous materials and musty odor. The invention material serves to solve the problems of the conventional materials, such as a reduced rate of operation resulting from the necessity for prolonged thermal sterilization for providing aseptic treated water and, particularly in the thermal sterilization using boiler water, the contamination of treated water with boiler chemicals.

摘要： In activated carbon obtained by subjecting a carbonaceous material to an activation treatment, the overall content of alkali metals is set at 100 ppm or less, or the overall content of heavy metals is set at 20 ppm or less and the overall content of alkali metals is set at 200 ppm or less. In cases where such activated carbon is used as a raw material in electronic devices, the formation of dendrites by the reductive deposition of alkali metals or heavy metals tends not to occur, so that problems such as short-circuiting or the like tend not to arise, and a good rate of self-discharge retention is shown.
