英文摘要: We designed and realized a novel centrifugal flow Singlet oxygen generator (CFSOG) that was originally proposed by Emanuel [Proc. SPIE 5448 (2004) 233]. In this device, singlet oxygen O(2)((1)Delta) is generated by the reaction of gaseous Cl(2) with aqueous basic hydrogen peroxide (BHP) that flows rapidly along an arc-shaped concave to form a rotating liquid layer. so that the nascent O(2)((1)Delta) generated in the liquid phase will be separated from it quickly to suppress the collision quenching loss of O(2)((1)Delta) with the help of the enormous centrifugal force produced by the rotating fluid. Our preliminary experiment shows that, because the specific reactive Surface area of this novel singlet oxygen generator (SOG) is much lamer than that of the jet-type SOG normally used in current chemical oxygen-iodine laser (COIL). enhanced performance of O(2)((1)Delta) yield similar to 60%. O(2)((1)Delta) partial pressure similar to 31 Torr, and an extremely high chlorine utilization within 96-98% have been realized.
