摘要
采用静态和动态法研究了D852螯合树脂对硝酸体系中Pd2+的吸附作用。实验结果表明,40℃时在酸性条件(pH≈0.5)下,该树脂对钯的静态饱和吸附容量为24.84 mg/g。用5%硫脲+0.5 mol/L HCl溶液做解析剂,室温下解析较为彻底,解析率达到94.7%以上。
Static and dynamic methods were used to investigate the adsorption properties of D852 chelating resin to palladium in nitric acid medium. The results showed that under the conditions of pH ≈ 0.5, the adsorption of palladium can reach 99%, and static saturated adsorption capacity reaches 24.84 mg/g. Using the 5% thiourea solution containing 0.5 mol/L hydrochloric acid as desorption agent, the desorption of palladium from the loaded D852 resin is thorough with the desorption rate over 94.7%.
