Reach adsorption equilibrium
WebMar 2, 2024 · With the increase of MW of HA from <1 kDa to >10 kDa, the time to reach adsorption equilibrium reduced from 180 to 120 min. It took more time for the hydrophilic fractions (140 min) to reach the equilibrium than for hydrophobic HA fractions (120 min). The Sips model fitted the adsorption equilibrium data of HA fractions on MIEX resin well. WebSep 12, 2016 · Adsorption equilibrium is investigated in a wide range of pressure (1 to 18 bar) at three temperatures (25, 35, and 45 °C). A study has been performed on the loading ratio correlation and Langmuir models for the adsorption.
