Treatment method of porous silicon dioxide

The invention relates to a treatment method of porous silicon dioxide. The method comprises: adding a first reactant and a second reactant to the porous silicon dioxide to form a mixture, wherein the first reactant and the second reactant are used to add specific functional groups in the porous silicon dioxide; stirring the mixture at a preset temperature; and washing the stirred mixture with the first reactant, and drying at a preset temperature to form a finished product. According to the method, the specific functional groups can be added into the porous silicon dioxide, so that the porous silicon dioxide can be used as an adsorbent of metals such as copper and nickel in the industry and a wastewater treatment agent; and the industrial wastes are recycled in the industry, and the method is beneficial to saving resources, protecting the environment and reducing the industrial cost. 本公开涉及多孔二氧化硅的处理方法。该方法包括：将第一反应物和第二反应物加入多孔二氧化硅中，形成混合物，其中，第一反应物和第二反应物用于在多孔二氧化硅中添加特定的官能团；将混合物在预设温度下搅拌；将搅拌后的混合物以第一反应物洗涤后于预设温度下干燥，以形成成
