用9335型阴离子交换树脂吸附经王水溶解的含钯物料，可以选择性吸附钯，铜、镍等杂质不被吸附。用8%氨水、40 g/L氯化铵解吸，98%以上的钯被解吸。吸附操作简单，解吸后的树脂可重复使用。
Palladium containing materials were dissolved by aqua regia and then adsorbed by 9335 anion exchange resin. Palladium can be selectively adsorbed, copper and nickel cannot be adsorbed. More than 98% palladium can be desorbed by 8% ammonia water and 40g/L ammonium chloride. The operation of adsorption is simple, and the desorbed resin can be reused.
