摘要: The uptake of tri-, tetra-, and hexa-valent actinides as well pertechnetate anions by some new multifunctional ion exchange resins has been investigated. resins, identified Diphonix A, for anionic Diphonix, contain the same geminally substituted diphosphonic acid groups bonded to a styrenic-based polymer matrix regular resin, plus strong base anion such tetralkylammonium (Diphonix A - Type 1 resins) or quaternized pyridinium 2 groups. Our measurements have shown that are effective resin in rapid from acidic solutions, while at time sorbing manner comparable existing commercial resins. failure perform equally explained consequence mutual interaction adjacent Uptake data also obtained with Se(IV). behavior toward Se(IV) solutions is 21 refs., 9 figs., 3 tabs.
