日本小西康裕研究团队提出,特定的微生物Shewanella细菌具有将中性溶液中金属离子和铂族金属离子还原成金属的功能。同时也具有吸附酸性溶液中稀有金属和贵重金属离子的功能。利用这些微生物的吸附功能,可以创制出常温下高速、高效回收稀贵金属的装置,将汽车催化剂、电子设备及液晶显示器含有金、铟及铂族元素的器件熔成液态,再吸附回收。有别于以往的化学法和物理法。利用Shewanella细菌吸附还原方法可以在常温常压下,对环境无污染,所使用微生物对人身无损害,而且Shewanella细菌培养容易,繁
Japan Xiaoxikangyu research team proposed that the specific microorganism Shewanella bacteria has the function of reducing metal ions and platinum group metal ions in neutral solution to metal. Also has the function of absorbing rare metals and precious metal ions in acidic solution. By utilizing the adsorption function of these microorganisms, a device capable of recovering precious metals at high speed and high efficiency at room temperature can be created, and devices containing gold, indium and platinum group elements in automobile catalysts, electronic equipment and liquid crystal displays are melted into a liquid state and adsorbed and recovered. Different from the previous chemical and physical laws. Shewanella bacterial adsorption reduction method can be at room temperature and pressure, the environment pollution-free, the use of microorganisms on the human body without damage, and Shewanella bacteria culture easy
