Elimination of hazardous metals is of extreme worry for their toxicity at trace levels and accumulation in the biosystem. Polyacrylonitrile ball clay nanocomposite was prepared by gamma irradiation at 20 kGy. Different analytical tools were applied to prove morphology, functional groups, and chemical structure for prepared composite; SEM, TEM, IR, XRD, and XRF. From TEM and XRD data expose the studied composite has nanoscale and crystalline. The adsorption of Cs⁺, Co²⁺ and Fe³⁺ onto studied material took place after 24 h. Second order was preceded by the kinetic system. The capacity and effect of pH on k_d reflect selectivity sequence; Co²⁺ > Fe³⁺ > > Cs⁺. Both Freundlich and Langmuir are applicable for investigated material. Finally, PAN/BC nanocomposite is suitable for the column technique.

消除有害金属因其痕量水平的毒性和在生物系统中的积累而令人极为担忧。聚丙烯腈球粘土纳米复合材料通过 20 kGy 的伽马辐射制备。应用不同的分析工具来证明制备的复合材料的形态、官能团和化学结构；SEM、TEM、IR、XRD 和 XRF。从 TEM 和 XRD 数据可以看出，所研究的复合材料具有纳米级和结晶性。Cs ⁺、Co ²⁺和Fe ³⁺在研究材料上的吸附发生在24 小时后。二阶先于动力学系统。pH对k _d的容量和影响反映了选择性顺序；Co ²⁺ > Fe ³⁺ > > Cs ⁺. Freundlich 和 Langmuir 都适用于研究的材料。最后，PAN/BC 纳米复合材料适用于柱技术。
