| 摘 要： | 在自行组装的带微计算机的流动注射分析装置上,建立了一个测定微量铀的方法。方法采用2-5-溴-2-吡啶)偶氮]-5二2乙氨基苯酚作铀的显色剂,以溴化十六烷基吡啶作增溶剂可直接在水溶液中进行测定。测定范围为0.1～2.0mg/L铀。在掩蔽剂存在下,常见的阴、阳离子不干扰测定。方法可适用于一般工艺处理过程溶液中微量铀的测定。分析速度为60样品/h。相对标准偏差小于2％。

| Abstract: | A spectrophotometric determination of uranium is presented by means of self-made Flow Injection Analysis System controlled by a microcomputer. The method uses 2- (5-bromo-2-pyridylazo) -5-diethyl -aminophenol (Br-PADAP) as chromogenic reagent of uranium at the presence of cetypyridium bromide (CPB) which makes the determination possible in aqueous solution. The common ions in the solution do not interfere the determination of uranium. The range of the determination is 0.1-2.0 mg/L (uranium). The relative standard deviation is less than 2%. About 60 samples can be analyzed per hour.The method is suitable for the analysis of microamount of uranium in waste water of uranium mills. |
