Contribution Evaluation of Physical Hole Structure, Hydrogen Bond, and Electrostatic Attraction on Dye Adsorption through Individual Experiments

Disagreements over various unanswered questions about contribution of the adsorption process and functional groups on dye still exist. The main aim this research was to evaluate contributions physical hole structure, hydrogen bond, electrostatic attraction adsorption. Three ideal representatives, namely, a sponge with porous P(AM) containing -CONH2 groups, P(AANa/AM) -COONa were chosen above contributions. methylene blue (MB) removal rates these three products compared through individual experiments. results revealed that structure did not play role in decreasing concentration. Hydrogen bond existed but remarkably reduce excellent demonstrated critical enriching contaminants from solution into solid adsorbent. could provide insights mechanisms for further research.
