The separation of itaconic acid (0.2 mmol·kg–1) from its aqueous solution is performed by dissolving tri-n-octylamine (TOA) in the biocompatible mixtures of 1-decanol + n-dodecane, dodecanol + n-dodecane, and oleyl alcohol + n-dodecane at different compositions. Also, the physical extraction data are presented with dodecane, oleyl alcohol, dodecanol, and 1-decanol.

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).

A new type of adsorbent was developed by incorporating magnetic properties using the coprecipitation method and amine functionality by the wet impregnation method. The adsorbent was characterized using Fourier transform infrared spectroscopy and field emission scanning electron microscopy along with energy-dispersive spectrometry, X-ray diffraction, and by point of zero charge analysis.
