Separation of Levulinic Acid Using Polymeric Resin, Amberlite IRA-67

Abstract

The adsorptive separation of levulinic acid (LA) from its aqueous solution was studied by using a commercial adsorbent and weakly basic anion exchange resin, Amberlite IRA-67 (IRA-67). The data were generated for equilibrium and kinetic studies, and to analyze the performance of IRA-67 on the removal efficiency. The equilibrium study was performed to see the effect of adsorbent quantity (0.25−1.5 g) and initial LA concentrations (2−4 g•L −1 ) at three different temperatures (298, 308, and 318 K). To determine the kinetics of adsorption process, concentration profile was achieved up to a time of 90 min at 298 K. It was observed that both the intake capacity (32−64 mg•g −1 ) and removal efficiency (6.75−72.5%) of IRA-67 were increased with an increase in the quantity of adsorbent (0.25−1.5 g) at 298 K. From the kinetics of adsorption, 50 min was considered as an equilibrium time. Different isotherm and kinetic models were used to determine the equilibrium and kinetic parameters of LA adsorption process. From the temperature study (298, 308, and 318 K), the thermodynamic properties were also estimated at three different LA concentrations.

Adsorption of 5-Hydroxymethylfurfural, Levulinic Acid, Formic Acid, and Glucose Using Polymeric Resins Modified with Different Functional Groups

“…It is important to describe the interaction between the adsorbate and surface properties of the adsorbent by various equilibrium adsorption isotherm model analyses. , In this work, the equilibrium adsorption data of 5-HMF, LA, FA, and glucose were determined using three adsorbents with different functional groups (XAD-4, XAD7HP, and XAD761) in a single-component solution system. Four temperatures of 288, 298, 308, and 318 K were chosen for the investigation of adsorption isotherms.…”

Conversion of levulinic acid to valuable chemicals: a review

“…However, due to poor adsorption effect, high cost, difficult regeneration, and other issues, the application of these methods was limited in industry. Uslu et al explored the separation of LA with Amberlite IR-67, a resin with a maximum adsorption capacity of 47.65 mg g -1 at temperatures of 298 K. 72 Datta and Uslu used commercial adsorbent Amberlite XAD-4 to adsorb LA with an adsorption capacity of 35.98 mg g -1 . 73 Although the adsorption selectivity of the separation of LA by ion exchange method is relatively high, a large amount of acid and alkali is needed during the regeneration of the adsorbent, resulting in a large amount of acid and alkali wastewater that can easily cause environmental pollution problems.…”
