摘　　要：我们合成了类似文献报道的聚硫醚（PTE）。通过各种性能实验,确定了试剂结构为HO CH2—S CH2OH,对Au、Pd、Pt、Rh、Ir、Ru、Os的吸附率在98％以上,且不吸附常见的非贵金属。分离富集效果优于文献。像PTE能吸附全部8个贵金属且饱和吸附容量非常大的吸着剂,尚属少见。A new adsorbent polythioether(PTE) synthesised by us for simultaneously adsorbing and determining all noble metals was represented and studied. The effects of temperature, heating time, acidity, different acid mediums, base metals were investigated intensively. Nearly all base metals did not interfere. The adsorption capacity of PTE for noble metals was very high (e. g. 750 mg Au/g dry adsorbent). The possible mechanism of adsorption was suggested. A reasonable PTE adsorption process followed by ICP-AES method for simultaneous determination of all noble metals was represented. The results found in the synthesized samples were satisfactory.
