The adsorbent has high adsorption performance and superparamagnetism, can be used for efficiently adsorbing pollutants such as heavy metal ions, can perform quick separation through control of external magnetic fields, and has a direct application value in purifying heavy metal ions of industrial wastewater, river, sea and the like.

Description

【Technical field】 [0001] The invention belongs to the field of chemical materials, and in particular relates to an adsorbent based on ferric oxide and nanometer zinc oxide and a preparation method thereof. 【Background technique】 [0002] With the development of globalization, the pollution of heavy metals to water bodies has attracted widespread attention all over the world, because they are highly toxic in water and easy to spread, which poses a great threat to human survival. Due to the rapid progress of industry, many industries such as leather manufacturing, metallurgy, battery production, electroplating, etc. produce a large amount of wastewater containing a variety of toxic heavy metal ions. As a traditional method to remove water pollution, adsorption has some obvious advantages, such as low cost, wide pH range, and easy operation. However, the traditional adsorbents are not ideal for heavy metal ion adsorption, and the separation process is complicated, easy to intr...
