| 中文摘要: |
| 铂族金属具有诸多优良的物化特性，广泛应用于制药行业、催化领域、微电子材料和饰品投资等。全球铂族金属储量少，研究铂族金属资源二次回收利用意义重大。微生物吸附机理主要包括静电吸附、离子交换、表面络合和氧化还原作用等，该法具有工艺简单、经济环保、选择性强等优点，因此，在金属离子回收领域有较大的发展前景，代表着未来技术的发展方向。 |
| 英文摘要: |
| Platinum group metals (PGMs) are widely used in various industries due to their specific physical and chemical properties, such as pharmaceutical industry, catalysis, microelectronic materials and jewelry materials. PGMs recovery from secondary sources is of great importance since they are rare in the earth's crust. The main mechanisms for biosorption are electrostatic adsorption, ion exchange, surface complexation and oxidoreduction. Recently, biological recovery of PGMs from wastewater has become an economic, eco-friendly and promising technology because of the high specificity and selectivity. |
