137Cs的裂变产额高(6.14%),半衰期(30a)长,γ射线能量为661.7keV。137Cs作为中毒性放射性核素,由于价态存在形式单一,容易进入环境,因此必须妥善处理和处置137Cs放射性废液。本文制备了一种对铯有特效的无机离子交换剂——亚铁氰化镍钾(KNiFC),其制备方法如下:向 137Cs has a high fission yield (6.14%), a long half-life (30a), and a gamma-ray energy of 661.7keV. 137Cs as a toxic radionuclide, due to the existence of a single valence state, easy access to the environment, it must be properly handled and disposed 137Cs radioactive waste. This paper prepared a special cesium ion exchange agent inorganic - nickel potassium ferrocyanide (KNiFC), which is prepared as follows: To
