Method for preparing seaweed biochar composite material from expired milk powder, obtained product and application

The invention discloses a method for preparing a seaweed biochar composite material from expired milk powder, an obtained product and application, the expired milk powder and seaweed powder are used as raw materials, and the seaweed biochar composite material is obtained through one-step high-temperature pyrolysis roasting. The method is easy to operate, safe and reliable, raw materials are easy to obtain, and effective utilization of waste biomass is achieved; the obtained composite material is good in catalytic effect and high in stability, the problem of secondary environmental pollution caused by metal ion leaching when a metal-based catalyst serves as a PMS activating agent can be solved, the problems of poor catalytic activity, instability and the like when a carbon-based catalyst serves as the PMS activating agent can be solved, and the removal efficiency of tetracycline hydrochloride is high. 本发明公开了一种利用过期奶粉制备海藻生物炭复合材料的方法及所得产品和应用，以过期奶粉和海藻粉为原料，通过一步高温热解焙烧得到海藻生物炭复合材料。本发明方法操作简单、安全可靠、原料易得，也实现了废弃生物质的有效利用；得到的
