摘要

研究了Stirosorb聚合物吸附剂对水溶液的吸附去除TBP的间歇模式和动态模式。在~0.9 g TBP/g吸附剂的负载下，Stirosorb聚合物吸附剂可以在不超过70°C的溶液温度下从水介质中去除TBP，残余有机物含量不超过10-11 mg/dm3。在Stirosorb吸附剂上去除含U（VI）和Pu（IV）的含磷化合物，而不消耗U（VI）和Pu（IV）。

Sorption Treatment of Aqueous Solutions with Stirosorb Sorbent to Remove TBP

The sorption treatment of aqueous solutions to remove TBP on the Stirosorb polymer sorbent in the batch and dynamic modes was studied. Stirosorb polymer sorbent allows removal of TBP from aqueous media at a solution temperature not exceeding 70°C to the residual organic matter content of no more than 10–11 mg/dm³ at a load of ~0.9 g TBP/g sorbent. A solution containing U(VI) and Pu(IV) is decontaminated from phosphorus-containing compounds on Stirosorb sorbent without solution depletion of U(VI) and Pu(IV).
