摘要/Abstract

摘要： 本文针对核电厂液态流出物排放的关键放射性核素进行了富集研究,制备了一种含六氰铁钴酸银钾和二氧化锰的复合型富集柱,通过实验研究了样品种类、流速、pH值、温度等因素对富集柱富集效率的影响,利用环境水样作为参考样品进行分析,结果良好。该方法可有效快速富集核电厂液态流出物中关键人工放射性核素,吸附效率可达90%以上,有效降低液态流出物中γ核素探测限;可缩短环境水样富集时间,适用于应急情况下环境水样监测。

Abstract: In this paper, a composite column containing silver potassium ferric cobaltate and manganese dioxide was prepared for the enrichment of key radionuclides from liquid effluents of nuclear power plants. The effects of sample type, flow rate, pH, temperature and other factors on the enrichment efficiency of the column were studied experimentally. The method can achieve rapid enrichment of key artificial radionuclides in environmental water samples and liquid effluents of nuclear power plants. The adsorption efficiency can reach more than 90%. This method can effectively reduce the detection limit of γ nuclides in liquid effluents, shorten the enrichment time of environmental water samples, and can be used for environmental water samples monitoring in emergency situations.

Key words: liquid effluents from nuclear power plants, environmental water samples, enrichment materials, artificial gamma nuclides, emergency monitoring
