Adsorption Behaviours of Sorbic Acid onto Polymeric Adsorbent Modified with 2-Carboxybenzoyl Group
Asian Journal of Chemistry
In the present study, a hypercrosslinked polymeric adsorbent (ZH-01) was employed to remove sorbic acid. The study focuses on the static equilibrium adsorption behaviours and the adsorption thermodynamics. Freundlich and Langmuir model give perfect fitting to the isotherm data. The adsorbing capacities for sorbic acid on ZH-01 is higher than on Amberlite XAD-4 within the temperature range 288-318 K, which is contributed to microporous structure and the polar groups on the network of ZH-01doi:10.14233/ajchem.2013.15738 fatcat:ieoxpe2yqfgx3dbquesamkjczu
