A procedure for the recovery of toluene, and the fluors 2,5-diphenyloxazole, and 1,4-bis-2-(5 phenyloxazolyl)-benzene from used scintillation fluid is described. Toluene is recovered by distillation, and the accumulated residue containing the fluors is dried, and subjected to vacuum distillation and recrystallization. The recovery of the two fluors is 75 and 70%, respectively. The method is relatively simple and could be used in many endocrine laboratories for economy and to reduce volumes of radioactive waste.
本文描述了一种从用过的闪烁液中回收甲苯、荧光剂2,5-二苯基恶唑和1,4-双[2-(5-苯基恶唑基)]苯的方法。通过蒸馏回收甲苯，将含有荧光剂的累积残渣干燥后进行真空蒸馏和重结晶。两种荧光剂的回收率分别为75%和70%。该方法相对简单，可用于许多内分泌实验室，以节省成本并减少放射性废物量。
