为了对云南某厂废水中的铂族金属Pt(Ⅳ)、Pd(Ⅱ)进行吸附回收ⅷ将大肠杆菌E.coli做为吸附剂ⅷ探讨其在较适工艺条件下的吸附率ⅷ并结合Pt(Ⅳ)、Pd(Ⅱ)的纯溶液吸附来探索E.coli对废水中铂族金属的吸附特性。Pt(Ⅳ)、Pd(Ⅱ)纯溶液吸附实验表明ⅷE.coli对两者吸附能力相当ⅷ吸附率分别为96.66%、97.68%?而在工业废水中ⅷE.coli对Pt(Ⅳ)的吸附率仅为19.5%ⅷPd(Ⅱ)的吸附率仍有97.20%。用SPSS软件对工业废水吸附结果进行显著性分析ⅷ综合吸附量、吸附率ⅷ可认为废水中存在的大量贱金属对 Pd(Ⅱ)的吸附没有产生影响ⅷE.coli 对 Pd(Ⅱ)表现除了较高的恒择吸附性?双相Pt(Ⅳ)-Pd(Ⅱ)溶液吸附实验也表现出了相似的结果。可见在Pt(Ⅳ)-Pd(Ⅱ)共存的溶液中ⅷE.coli对Pd(Ⅱ)具有较高恒择吸附性。

To recover the platinum group metal Pt(IV) and Pd(II) in the waste water of a factory in Yunnan Province, the E.coliwas used as adsorbent to investigate the adsorption rate under better conditions and adsorption of pure Pt(IV), Pd(II) solution were used to explore the adsorption characteristics ofE.coli on the platinum group metals in wastewater. Pure Pt(IV) and Pd(II) solution adsorption experiments showed that two adsorption capacity of E.coli is equal, and the adsorption rate was 96.66% and 97.68% respectively; in industrial wastewater, the adsorption rate ofE.coli on Pt(IV) was 19.5%, and the adsorption rate of Pd(II) was still 97.20%. Analysis results of the adsorption results of industrial wastewater using SPSS software showed the adsorption of Pd(II) was not affected by the presence of a large number of base metals in wastewater, and theE.colishows Pd(II)-selective sorption behavior; the similar results were also demonstrated by Pt(IV)-Pd(II) solution adsorption experiments. In the solution of Pt (IV)-Pd (II), the E.coli has a high Pd(II)-selective adsorption property.
