Embodiment 1
[0022] (1) Weigh 3g of oxidant ammonium persulfate and dissolve it in 30mL 0.5mol / L protonic acid solution, and record it as solution A; take 1mL aniline monomer and dissolve it in 20mL 0.5mol / L protonic acid solution, and record it as solution B; The protic acid is a mixture of hydrochloric acid and dodecylbenzenesulfonic acid, and the molar ratio of the two is 0.6:1; the solution A and the solution B are ultrasonically dispersed and then cooled to -5~0°C;
[0023] (2) Slowly drop solution A into solution B to obtain a mixed solution;
[0024] (3) Static oxidation polymerization reaction occurs at -5~0℃, and the reaction time is 2~18h;
[0025] (4) After the reaction is completed, the reaction product is filtered and washed, dried in vacuum and then ground and dispersed to obtain the modified polyaniline adsorbent.
[0026] The modified polyaniline adsorbent prepared in this embodiment is as follows: figure 1 As shown, it is composed of polyaniline with a micro-nano seconda...
