摘要
A process for isolating 17O from water and a process for concentrating 17O by using the same are provided. The process for isolating 17O from water includes: mixing 17O-containing water with formaldehyde to prepare an aqueous formaldehyde solution; heating the aqueous formaldehyde solution to generate a vapor mixture containing water vapor and formaldehyde vapor; and obtaining 17O-depleted water, residual formaldehyde, and a gas mixture containing hydrogen and 17O-enriched carbon monoxide, through photodissociating the vapor mixture. An 17O-enriched water production process includes: an operation of adding hydrogen to the gas mixture to induce a catalytic methanation reaction to synthesize methane (CH4) and 17O-enriched water (H217O) through methanation, the operation being carried out following the process for isolating 17O from water.
