When the emulsion is added into the mixture of hydrochloric acid and anhydrous ethanol, negative charges on the emulsion particles' surfaces are neutralized, the repulsive force between the emulsion particles vanishes, and the emulsion rapidly agglomerate into larger clusters. In addition, when the emulsion particles are aggregated, the emulsion particles are disassembled, the chain segment shrinks and aggregates to generate internal stress, then a large number nanopore are generated to overcome the internal stress. The nanosponge adsorbents prepared by ion condensation method have a certain removal effect on methylene blue, among which WPU-4,4.62 has the best adsorption capacity.
