▎ 摘　　要

NOVELTY - Sintered nanoparticle compound comprises zeolite, silver nitrate, a silver dioxide nanoparticle, and graphene, where the zeolite is a core element impregnated with the silver nitrate and the silver dioxide nanoparticle, and the impregnated zeolite core element is encapsulated in a graphene monolayer to form a sintered nanoparticle. USE - The compound is useful for sterilizing and/or treating water (claimed). ADVANTAGE - The compound avoids excessive repetition in method. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) sterilizing and/or treating (M1) water, comprising providing the sintered nanoparticle compound, and contacting water to be treated with the sintered nanoparticle compound, where the water is sterilized and/or treated; (2) making (M2) a sintered nanoparticle compound, comprising providing a zeolite, providing a silver nitrate, providing a silver dioxide nanoparticle, providing a graphene, combining a core element of the zeolite with a solution of silver nitrate and/or silver dioxide nanoparticle, and mixing the solution to provide equal distribution, where the zeolite core is impregnated with the silver nitrate and/or silver dioxide nanoparticle; (3) sterilizing and/or treating (M3) water, comprising providing the EGAC compound, and contacting water to be treated with the EGAC compound, where the water is sterilized and/or treated; and (4) making (M4) the EGAC compound, comprising providing a granulated activated charcoal, providing a silver nitrate, combining the granulated activated charcoal with a solution of silver nitrate and mixing to uniformly combine the granulated activated charcoal with the silver nitrate to form a granulated activated charcoal and silver nitrate composite, providing a silver dioxide nanoparticle and mixing it with the granulated activated charcoal and silver nitrate composite, and placing the granulated activated charcoal with silver nitrate and silver dioxide nanoparticle in a negative pressure autoclave.
