• PDVB/PMAEM IPN exhibited greater adsorption capacity of salicylic acid than that of 5-sulfosalicylic acid.
• Greater adsorption capacity of SA onto PDVB/PMAEM IPN was proved by the thermodynamic analysis.
• Greater adsorption capacity of salicylic acid onto PDVB/PMAEM IPN was attributed to its' stronger hydrophobicity.
Hydrophobic-hydrophilic macroporous polydivinylbenzene/polymethylacrylethylenediamine IPN (PDVB/PMAEM IPN) was synthesized indirectly through the strong forced compatibility. The effects of the hydrophobicity of adsorbate on the adsorption of salicylic acid and 5-sulfosalicylic acid onto the hydrophobic-hydrophilic PDVB/PMAEM IPN were investigated. PDVB/PMAEM IPN exhibited greater adsorption capacity of salicylic acid than that of 5-sulfosalicylic acid. The absolute values of ΔH, ΔG and ΔS of the adsorption of salicylic acid onto PDVB/PMAEM IPN were greater than those of 5-sulfosalicylic acid, indicating the adsorption of salicylic acid onto PDVB/PMAEM IPN was more welcome. Adsorption mechanism proved that greater adsorption capacity of salicylic acid onto PDVB/PMAEM IPN than that of 5-sulfosalicylic acid was attributed to the stronger hydrophobicity of salicylic acid.
Hydrophobic-hydrophilic PDVB/PMAEM IPN was synthesized indirectly through the strong forced compatibility. PDVB/PMAEM IPN exhibited greater adsorption capacity of salicylic acid than that of 5-sulfosalicylic acid because of its' stronger hydrophobicity. Greater adsorption capacity of salicylic acid onto PDVB/PMAEM IPN was proved by the thermodynamic analysis.Figure optionsDownload as PowerPoint slide
