摘　　要：描述了2 37Np在不同材质 (聚四氟乙烯、聚氯乙烯、聚丙烯、玻璃、有机玻璃和尼龙 )上和不同实验条件 (p H=2无土 ,p H=8有土、无土 )下的吸附情况。实验结果表明 :所选的材料在低 p H值无土和高 p H值有土的情况下对 2 37Np的吸附是很弱的 ,高 p H值无土的情况下吸附较强。This paper describes the sorption of 237 Np on container wall of materials(usually used in experiments) under different conditions (i.e., pH 2.0 and 8.0 without loess and pH 8.0 with loess). The results indicate that in most cases the sorption of 237 Np is weak on container wall of the materials used in this experiment.However,the sorption of 237 Np on container wall of the materials is strong if pH of solution is increased to 8.0 and no loess added.
