以聚丙烯酰胺和白云石为原料，合成了一种新型、高效、经济的吸附剂（PAA-Do），并将其用于水中铀酰离子的去除。采用FTIR、SEM-EDX和XRD等技术对新材料进行了表征。根据Langmuir方程，PAA-Do的最大吸附容量（Qm）为0.477 mol kg−1。吸附动力学符合准一级动力学方程。吸附剂的回收可以通过1.0 mol L− 1 HCl进行。本研究的结果表明，PAA-DO复合材料是良好的吸附剂去除铀酰的候选人。
A new, effective, and economic adsorbent (PAA-Do), consist of Polyacrylamide and Dolomite was synthesized chemically and used for removal of uranyl ions from aquatic medium. Characterization of new material was carried out by FTIR, SEM–EDX and XRD techniques. The maximum adsorption capacities (Qm) for PAA-Do was found by the Langmuir equation to be 0.477 mol kg−1. Adsorption kinetic was well-described by the pseudo first order kinetic. Recovery of adsorbent can be carried out by 1.0 mol L−1HCl. The results of this study indicate that PAA-Do composites are good adsorbent candidates for uranyl removal.
