摘要
采用离子交换法研究了717强碱性阴离子交换树脂、人造沸石去除饮用水中总α放射性的效果。以铀为示踪剂，717树脂和人造沸石对自来水体系中铀α放射性的去除率分别为98．0％、47.2％。应用717树脂作为交换剂，处理总α超标饮用水的结果表明，经交换后水样的总α放射性均达到饮用水标准的要求。
The effect of reducing the gross α radioactivity in drinking water by ion exchangers, the strong alkaline anion resin 717 and cation exchanger,artificial zeolite,was experimented. The reduction ratios of gross α in drinking water were 98. 0% and 47. 2% respectively,when U was used as the tracer. When 717 resin was used as the ion exchanger to treat the water with excess gross α radioactivity,the gross α in the resultant water would be in compliance with the hygienic standard of the drinking water.
