Abstract: The present invention provides a new method for fixing carbon dioxide. The method for fixing carbon dioxide of the present invention includes a contact step of bringing a mixed liquid containing sodium hydroxide and further containing at least one of a chloride of a Group 2 element or a chloride of a divalent metal element into contact with a gas containing carbon dioxide.

Abstract: An example sterilizing apparatus comprises a medical fluid container storing a medical fluid containing alcohol, a gas cylinder filled with pressurized carbon dioxide gas, and a spray gun connected with the medical fluid container and the gas cylinder. The sterilizing apparatus being configured to spray the medical fluid into a target space under action of the carbon dioxide gas injected from a tip nozzle of the spray gun. The sterilizing apparatus further comprises a control valve to increase and/or decrease an amount of the carbon dioxide gas to be injected, thus adjusting an amount of the medical fluid to be sprayed.

Abstract: An apparatus for sterilizing and disinfecting a target space by spraying a chemical including alcohol includes a spray gun to which a chemical container containing a sterilizing and disinfecting chemical including alcohol is attachable, a gas cylinder filled with a compressed carrier gas that does not react with alcohol, and a pressure reducing valve for decompressing the carrier gas discharged in a vaporized state from the gas cylinder to a predetermined pressure, and is constructed so that the pressure reducing valve and the spray gun are directly connected with a gas hose and mounted on a common truck. The sterilizing and disinfecting apparatus can operate with a simple structure requiring no power supply, and is much lighter in weight compared to conventional apparatuses.

Abstract: An apparatus for sterilizing and disinfecting a target space by spraying a chemical including alcohol includes a spray gun 4 to which a chemical container 7 containing a sterilizing and disinfecting chemical including alcohol is attachable, a gas cylinder 1 filled with a compressed carrier gas that does not react with alcohol, and a pressure reducing valve 2 for decompressing the carrier gas discharged in a vaporized state from the gas cylinder 1 to a predetermined pressure, and is constructed so that the pressure reducing valve 2 and the spray gun 4 are directly connected with a gas hose 3 and mounted on a common truck 5. The sterilizing and disinfecting apparatus can operate with a simple structure requiring no power supply, and is much lighter in weight compared to conventional apparatuses.
