器壁吸附对镅分配系数测定的影响

摘要: 测定了￣２４１Ａｍ在溶液和膨润土等吸附材料之间的分配系数以及器壁吸附百分率，讨论了器壁吸附对分配系数测定的影响。实验结果表明，空白实验管壁的吸附比含有固体吸附材料时管壁的吸附高得多；对于高分配系数的吸附材料，器壁吸附对Ｋ＿ｄ测定的影响可以忽略，但对低分配系数的材料，应该考虑器壁吸附的影响。

Abstract: THE INFLUENCE OF CONTAINER WALL SORPTION ON SORPTION RATIO OF ~(241)AMZENG JISHU；XIA DEYING(Chian Institue of Atomic Energy,P,O,Box 275，Beijing，102413）ABSTRACT In this paper，the container wall sorption percentage and the sorption ratio of Am betweensolution and such sorption materials as bentonite are studied with the HPGe detector connected-with S-85 multichannel system，the influence of container wall sorption on sorption ratio also isdiscussed．The results show that the container wall sorption with solid sorptive materials is lowerthan that without solid sorptive materials. The container wall sorption should be considered forthe sorptive materials with low sorption ratio values and can be neglected for those with highsorption ratio values.Key words Container wall Sorption ratio Sorption~(241)Am
