一、前言在核工业生产中,为了控制工艺过程,经常需要监测工艺尾弃液或排放废水中的低浓铀(0.05—5mg/L)。到目前为止,采用激光萤光法的铀分析器虽然已能监测低至十亿分之几(ppb)数量级的痕量铀,但更低浓度的测量尚未见到。本仪器是一种用于过程控制的湿法化学自动分析器,能在生产线上自动监测0.03—30mg/L的低浓铀,对一些实际的样品体系进行测量,取得了较好的结果,现已由苏州光学仪器厂生产。
I. Preface In nuclear industrial production, in order to control the process, it is often necessary to monitor the tailings of the process or to discharge low enriched uranium (0.05-5 mg / L) from wastewater. So far, uranium analyzers using laser fluometry have been able to monitor trace amounts of uranium down to the order of a few parts per billion (ppb), but lower concentrations have not yet been observed. This instrument is a wet chemical analyzer used for process control. It can automatically monitor low enriched uranium (0.03-30mg / L) on the production line and measure some practical sample systems. Good results are obtained. Suzhou Optical Instrument Factory has been produced.
