The efficiency of the sorbent prepared by immobilization of [Iron(II)hexacyanoferrate(II)] on clinoptilolite--marked as ZEOFe--in reduction of the radiocaesium Cs-137 has been in vivo investigated in sheep. It was found that an application of this modified clinoptilolite affected both primary and secondary resorption of Cs-137 also by interrupting the enteral cycle of radiocaesium in sheep. It was proved that ZEOFe accelerated approx. twice the excretion of Cs-137 from sheep's body. The whole effect resulted in 15 to 50 times lowering of the equilibrium concentration of radiocaesium in the case of constant intake of the contaminated feed and simultaneous application of 50 grams of ZEOFe daily. The actual reduction depends mainly on the way of administration. The reduction of Cs-137 by non-modified clinoptilolite--ZEO--has been investigated, too. More than 10x lower sorption efficiency has been observed in comparison with ZEOFe.
通过将[亚铁氰化铁（II）]固定在斜发沸石上制备的吸附剂（标记为ZEOFe）对放射性铯Cs - 137的还原效率已在绵羊体内进行了研究。结果发现，这种改性斜发沸石的应用通过中断绵羊体内放射性铯的肠循环，对Cs - 137的初次和二次吸收均有影响。事实证明，ZEOFe使Cs - 137从绵羊体内的排泄速度加快了约两倍。在持续摄入受污染饲料并每天同时施用50克ZEOFe的情况下，整体效果使放射性铯的平衡浓度降低了15至50倍。实际的降低程度主要取决于给药方式。未改性的斜发沸石（ZEO）对Cs - 137的还原也进行了研究。与ZEOFe相比，观察到其吸附效率低10倍以上。
