摘　　要：研究了聚苯硫醚（ＰＰＳ）在硝酸、硫酸和盐酸介质中对贵金属钯的吸附行为及振荡吸附时间、酸度、钯浓度对吸附的影响。结果表明：在不同的酸介质中ＰＰＳ对钯均有一定量的吸附，其饱和吸附容量可达１０．７８±１．０９ｍｇ／ｇ树脂，且有很好的吸附选择性，还探索了解吸剂及从混合离子溶液中回收钯的途径。The adsorption of Pd(II)from various acidic mediums(HNO3,H2SO4,HCI)on the polyphenylene sulfide and the effects of equilibrium time,acidity,and concen tration of palladium on the adsorption have been studied.The results showed that Pd(II)can be selectively adsorbed from acidic mediums and the adsorption capacity of palladium of l0.78±1.09 mg per gram resin can be obtained.The methods of deadsorption and recovery of palladium from mixed ion aqueous solutions have also been provided.
