摘要
本文使用自制的负载有巯基碳粉的泡塑分离富集钯。试验了该富集剂对钯的最佳吸附与解脱条件以及２３种共在离子的影响。对低钯管理样进行加标回收实验，结果表明，钯的平均回收率为８９．６５％，ＲＳＤ＝３．７１％。
A new kind of foam plastic was made for theseparation and concentration of palladium. In themedium of 1% HCl,palladium can be adsorbed on themodified foam plastics completely by controlling theflow rate at 3mL/min. The adsorbed palladium can beduted with 2% NaBrO_3-2mol/L HCl as elutant,anddetermined by FAAS.23 coexisting ions have nointerference with the determination of palladium bythis method. The recoveries of palladium in samplesand the relative atandard deviation are satisfactory.
