改性泥炭对^(169)Yb吸附性能的研究

Study on the Absorption of 169Yb on the Modified Peat

用静态法研究了化学改性泥炭对１６９Ｙｂ的吸附交换性能．讨论了改性泥炭中的腐植酸对１６９Ｙｂ的吸附平衡时间，ｐＨ对吸附率Ｅ％的影响，不同方法处理的泥炭对分配系数Ｋｄ的影响，改性泥炭对１６９Ｙｂ的吸附服从Ｆｒｅｕｎｄｌｉｃｈ吸附等温式．

The absorption and exchange behaviors of 169Yb on chemical modified peat are studied by the static method in this paper. Several problems are discussed, including on 169Yb the absorption equilibrium time of the pH effect on the absorption efficiency of E% and the effect of the modified peat which has been treated by different methods on the distribution coefficient Kd. The absorption of modified peat on 169Yb obeys the Freundlich isotherm equation.
