摘要: The widespread use of platinum in high-tech and catalytic applications has led to the production diverse Pt loaded wastewaters. Effective recovery strategies are needed for treatment low concentrated waste streams prevent pollution stimulate this precious resource. biological five common environmental Pt-complexes was studied under acidic conditions; chloro-complexes PtCl42- PtCl62-, amine-complex Pt(NH3)4Cl2 pharmaceutical complexes cisplatin carboplatin. Five bacterial species were screened on their potential; Gram-negative Shewanella oneidensis MR-1, Cupriavidus metallidurans CH34, Geobacter metallireducens, Pseudomonas stutzeri, Gram-positive Bacillus toyonensis. Overall, PtCl62- completely recovered by all while only S. C. able recover quantitatively (99%), presence H2 as electron donor at pH 2. Carboplatin partly (max. 25% 7), whereas no observed case Pt-tetraamine complex. Transmission microscopy (TEM) revealed both intra- extracellular particles. Flow cytometry based microbial viability assessment demonstrated decrease number intact cells during reduction indicated be most resistant species. This study showed effective complete three Pt-complexes, estimated fate transport wastewater plants natural environment.
