Preparation method of treating heavy metal copper ions by microbial fuel cell

The invention discloses a preparation method of treating heavy metal copper ions by a microbial fuel cell. A cathode of the microbial fuel cell is made from a carbon nano tube; the metal ions perform a reduction reaction; and a simple substance, copper, is separated out on the cathode. The method comprises the following steps of weighing a certain amount of the carbon nano tube, coating the cathode of the microbial fuel cell with the carbon nano tube, and allowing the simple substance copper to be separated out after the microbial fuel cell operates for a period of time. According to the novel copper preparation method by the microbial fuel cell, the carbon nano tube is used for reducing reduction activation voltage; the copper ions perform the reduction reaction; at the same time, power can be generated; organic pollutants can be treated; a system is simple; and a reduction rate of the copper is high. 本发明公开了种微生物燃料电池处理含重金属铜离子的制作方法。微生物燃料电池的阴极材料使用碳纳米管，使金属离子发生还原反应，在阴极析出铜单质；包括以下步骤：量取定量的碳纳米管，把碳纳米管涂布到微生物燃料电池阴极上，微生物
