一种脱汞剂及脱汞方法
摘要：
本发明属于脱汞剂技术领域，具体涉及一种脱汞剂及脱汞方法；该脱汞剂由铝粉和铁粉组成，所述铝粉与铁粉的质量比为1.5:1—9:1。本发明技术方案中的脱汞剂能实现高低含汞浓度的污酸中汞的高效脱除，脱汞剂与污酸中其它重金属离子副反应少，脱汞选择性好、汞提取率高；脱汞剂对污酸酸度具有很好的适应性，适用于pH为0.8-4.0的污酸废水中汞的脱除，相比传统脱汞方法，在还原过程中消耗了废水中的酸从而降低了废水酸度，无需再加碱中和。方法简单、容易操作，满足工业化应用。
摘要（英）：

The invention belongs to the technical field of mercury removal agents, and concretely relates to a mercury removal agent and a mercury removal method. The mercury removal agent is composed of aluminum powder and iron powder according to a mass ratio of 1.5:1 to 9:1. The mercury removal agent can realize the high-efficiency of mercury in contaminated acid containing high or low mercury, has few side reactions with other heavy metal ions in the contaminated acid, and has a good mercury removal selectivity and a high mercury extraction rate; the mercury removal agent has excellent adaptability to the acidity of the contaminated acid, and is suitable for removing mercury from contaminated acid wastewater with the pH value of 0.8-4.0; and compared with traditional mercury removal methods, the method in the invention takes away acids in the wastewater to reduce the acidity of the wastewater without adding an alkali for neutralization. The method is simple, is easy to operate, and can meet industrialization application.
