| titleOfInvention | Preparation method and application of in-situ nitrogen-doped carbon microsphere adsorbent |
| abstract | A preparation method and application of an in-situ nitrogen-doped carbon microsphere adsorbent relate to a preparation method and application of an adsorbent. The invention aims to solve the problems of slow adsorption rate, small adsorption capacity and poor universality of the existing water treatment adsorbent. The method comprises the following steps: firstly, synthesizing nitrogen-containing polymer microspheres; secondly, high-temperature carbonization; and thirdly, activating with high-temperature alkali to obtain the in-situ nitrogen-doped carbon microsphere adsorbent. The method for purifying the sudden micro-polluted water body comprises the following steps: and (3) adding the in-situ nitrogen-doped carbon microsphere adsorbent into the micro-polluted sudden water body, stirring and reacting for 2-5 min, and filtering the adsorbent to obtain the treated water body. The method for enriching trace contaminants in water is as follows: adding the in-situ nitrogen-doped carbon microsphere adsorbent into a water body containing trace pollutants, and stirring for reacting for 2-5 min to obtain treated water; the invention can obtain the in-situ nitrogen-doped carbon microsphere adsorbent. |
