After the iron ions are added, most of dye can be removed through the synergistic effect of the iron ions and the hydrogen peroxide, and the removal rate of the Congo red by the porous carbon material is greatly improved through ultrasonic treatment.
According to the preparation method of the heteroatom porous carbon, the adsorption mechanism of the porous carbon on Congo red dye is that organic matters and hydrogen peroxide are diffused to active sites on the surface of a catalyst and are adsorbed, then under the catalytic action of the catalyst, iron ions and the hydrogen peroxide are reacted in series to generate hydroxyl radicals, and the hydroxyl radicals have high oxidation activity, so that a radical chain reaction is initiated, the organic matters are oxidized and degraded, and finally, degradation products are desorbed from the surface of the catalyst and are diffused in a main body of a solution, so that the efficient and rapid degradation of the organic matters is realized.
The preparation method takes the cicada slough as a precursor, and adopts a one-step method to prepare a novel heteroatom porous carbon material as a Fenton-like reagent catalyst. Then the catalyst is enhanced in catalysis and stability through the synergistic effect of sonochemistry and Fenton reaction, and the performance of the catalyst in the aspect of removing industrial pollution is improved. The technology has the advantages of wide raw material source, low cost, simple preparation process and great application potential in the aspect of dye removal.
