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。
Ion exchange method was used to study the effect of 717 strong basic anion exchange resin and artificial zeolite to remove total α radioactivity in drinking water. With uranium as tracer, 717 resin and artificial zeolite on the water system uranium α radioactivity removal rates were 98.0%, 47.2%. Using 717 resin as the exchange agent, the results of treating total α-over-drinking water showed that the total α-radioactivity of the water samples after the exchange met the drinking water standard requirements.
