摘　　要：三聚磷酸二氢铝(ATP)对一价正离子有吸附性。实验考察了吸附剂用量、pH值、辐照量对吸附银离子的影响。结果表明:提高吸附剂用量不会改变ATP晶体结构;提高pH值能降级ATP片层厚度,增大层间距,提高吸附性;提高辐射量会使去除率降低,降低吸附性。Dihydrogen aluminum triphosphate （ATP） is adsorbed on one - valence positive ions. The effects of the amount of adsorbent, pH and irradiation on the adsorption of silver ions were investigated. The results show that increasing the amount of adsorbent does not change the structure of ATP crystals, increase the pH to reduce the thickness of the ATP layer, increase the interlayer spacing and improve the adsorption. The increase of the radiation will reduce the removal rate and reduce the adsorption.
