摘　　要：为研发高效易回收的碘吸附材料,本研究制备了铜基铂(PCC)材料,将铂包覆在铜粉表面,用于气态碘的吸附研究。并探索氯铂酸用量、反应温度等对PCC吸附碘的影响,通过正交实验优化制备工艺,并通过能量色散X射线光谱仪(EDX)和X-射线光电子能谱(XPS)测试探究PCC吸附气态碘的机理。结果表明,PCC对气态碘具有高吸附性能和回收率,对气态碘吸附容量可达1279 mg/g,碘的回收率>98.5%。本研究结果可为^(125)I生产工艺中碘的捕集和回收提供参考。To develop efficient and easily recoverable iodine adsorbent materials,a platinum coated copper(PCC)material coated with platinum on the surface of copper powder was prepared and used for the adsorption of gaseous iodine.During the PCC preparation process,this study explored the effects of reaction conditions such as chloroplatinic acid dosage,reaction temperature on the adsorption performance of PCC.The preparation process was optimized by orthogonal experiment.The results showed that PCC had high adsorption performance and recovery rate for gaseous iodine.The adsorption capacity of PCC for gaseous iodine could reach 1279 mg/g,and the recovery rate of iodine was more than 98.5%.The mechanism for the adsorption of gaseous iodine by PCC was then probed and proposed by EDX and XPS tests.The research results laid a foundation for the capture and leaching recovery of iodine in the process of production of iodine-125.
