Abstract

Abstract The sorption of 241Am3+, 85Sr2+ and 137Cs+ by calcium, strontium and barium alginates has been studied under different operation conditions. The most prominent adsorption was found in the pH range of 5–6 for all systems, even if the observed dependence on the acidity of the solution was small. The most favourable time for the adsorption process was found to be about 2 h for calcium alginate and 4 h for the other two sorbents.

生物源吸附剂从液体放射性废物中吸附选定的放射性核素：碱土褐藻酸盐

摘要研究了藻酸钙、锶和钡在不同操作条件下对241Am3+、85Sr2+和137Cs+的吸附。对于所有系统，最显著的吸附发生在5–6的pH范围内，即使观察到的对溶液酸度的依赖性很小。发现藻酸钙吸附过程的最有利时间约为2小时，其他两种吸附剂吸附过程的最佳时间约为4小时。
