Provide are an ionic liquid composition for a carbon dioxide separation membrane, a carbon dioxide separation membrane retaining the composition in voids, and a carbon dioxide concentration apparatus provided with the carbon dioxide separation membrane that can be used to separate carbon dioxide from high partial pressure to low partial pressure. The permeability of COand COselectivity ratio of the carbon dioxide separation membrane can be improved, and carbon dioxide from high partial pressure to a low partial pressure of 1 kPa or lower can be selectively separated and recycled by using an ionic liquid composition prepared by combining: an ionic liquid (I) that is an aminium having one or more primary or secondary amino groups and an ethylenediamine or propylenediamine backbone in the cation; and an ionic liquid (II) in which the cation has no primary or secondary amino group and the anion is an oxoacid anion.

An object is to provide a method of manufacturing luminescent nanocarbon with which the luminescent nanocarbon can be efficiently manufactured in large amounts. This method is to manufacture luminescent nanocarbon (Product) from a raw material aqueous solution that contains a carbon source compound and a nitrogen source compound. This method includes a reaction step of heating the raw material aqueous solution from a storage container (Reservoir) in a heating section (Furnace) to react the raw material aqueous solution at a reaction temperature of 100&#xb0; C. or higher and 500&#xb0; C. or lower and a cooling step of cooling a reaction solution that contains a reaction product generated in the reaction step. The cooling step is carried out in a bath (Ice bath).

A gas separation and recovery apparatus that separates and recovers nitrogen oxides from a gas mixture includes: a liquid storing portion that stores a liquid, the liquid absorbing the nitrogen oxides; a gas-liquid contacting portion in which the liquid and the gas mixture contact with each other; and a liquid recovering portion that recovers the liquid after the liquid contacts the gas mixture. The liquid is an ionic liquid that chemically absorbs the nitrogen oxides.
