在传统的软水器中，向强酸阳离子（SAC）树脂中加入少量的强碱阴离子（SBA）树脂，可以很好地去除铀和镭。在含有25 pCi/L镭和120 ug/L铀的井水上进行试验时，含有10%SBA和90%SAC树脂的混床在氯化钠再生循环操作期间提供了含有小于1 pCi/L镭和20 ug/L铀的产品水。其他测试表明，过多的阴离子树脂或分层树脂床导致过量的镭和铀泄漏。此外，氯化钾是从废树脂中洗脱镭的优于氯化钠的再生剂。 包括31个参考文献、表格、图表。

Adding a small amount of strong base anion (SBA) resin to the strong acid cation (SAC) resin in a conventional water softener provides good uranium and radium removal. In tests on a well water containing 25 pCi/L radium and 120 ug/L uranium, a mixed bed containing 10 percent SBA and 90 percent SAC resin provided a product water with less than 1 pCi/L radium and 20 ug/L uranium during cyclic operation with sodium chloride regeneration. Additional tests indicated that too much anion resin or stratified resin beds caused excessive radium and uranium leakage. Also, potassium chloride was a superior regenerant to sodium chloride for elution of radium from the spent resin. Includes 31 references, tables, figures.
