[18F]Fluoride was trapped from [18O]water in high yield by ion exchange on a microporous carbon prepared by controlled oxidation to produce a cationic surface with an exchange capacity of about 350 microequiv/g. The [18F]fluoride could be recovered by displacement with aqueous K2CO3. The cationic carbon offered a dimensionally rigid matrix of high thermal stability. It was characterized with respect to chemical reactivity and selectivity for anion exchange.
通过在由可控氧化制备的微孔碳上进行离子交换，以高收率从[18O]水中捕获[18F]氟化物，从而产生具有约350微当量/克交换容量的阳离子表面。[18F]氟化物可用碳酸钾水溶液置换回收。阳离子碳提供了具有高热稳定性的尺寸刚性基质。对其化学反应性和阴离子交换选择性进行了表征。
