| titleOfInvention | Preparation and application methods of sulfur dioxide rice straw adsorbent |
| abstract | The invention discloses preparation and application methods of a sulfur dioxide rice straw adsorbent. The preparation method mainly comprises the steps of: washing rice straw, drying and crushing; soaking the rice straw powder in a swelling agent for sufficiently swelling, then washing with water to be neutral, filtering and drying; soaking the rice straw powder after swelling treatment in an oxidant solution for sufficiently soaking, then washing and filtering; and carrying out amination reaction on the rice straw powder after oxidant treatment and an aminating agent solution at 70-90 DEG C, after sufficient reaction, washing, filtering and drying to obtain the rice straw adsorbent for SO2 adsorption. The SO2 rice straw adsorbent is used by wetting with water until the moisture content is not less than 100%. According to the completion and disclosure of the invention, a bran-new way is opened for rice straw application, the rice straw value is increased, at the same time, a new adsorbent is provided for adsorptive purification of SO2 gas, and the types of SO2 adsorbents are enriched. |
