Preparation method and application of in-situ nitrogen-doped carbon microsphere adsorbent

Abstract

The invention provides a preparation method and an application of an in-situ nitrogen-doped carbon microsphere adsorbent, relates to a preparation method and an application of an adsorbent and aims tosolve the problems of low adsorption rate, small adsorption capacity and poor universality of an existing water treatment adsorbent. The method comprises steps as follows: step one, synthesizing nitrogen-containing polymer microspheres; step two, performing high-temperature carbonization; step three, performing high-temperature alkaline activation to obtain the in-situ nitrogen-doped carbon microsphere adsorbent. A method for purifying micro-pollution emergency water comprises steps as follows: the in-situ nitrogen-doped carbon microsphere adsorbent is added to the micro-pollution emergency water, the water is stirred and subjected to a reaction for 2-5 min, and after the adsorbent is filtered, the treated water is obtained. A method for enriching trace pollutants in water by the in-situnitrogen-doped carbon microsphere adsorbent comprises steps as follows: the in-situ nitrogen-doped carbon microsphere adsorbent is added to water containing the trace pollutants, the water is stirredand subjected to a reaction for 2-5 min, and the treated water is obtained. The in-situ nitrogen-doped carbon microsphere adsorbent can be obtained.
