Shabani, Mahtab published the artcileLong-lasting adsorption of golden flower oil on polyvinyl alcohol/clinoptilolite (PVA/CP) xerogel particles, COA of Formula: C13H18O3, the main research area is polyvinyl alc clinoptilolite xerogel golden flower oil adsorption.
The present work aimed to study the adsorption and desorption characteristics of Golden Flower Oil (GFO) on xerogel particles made of Clinoptilolite (CP), a natural zeolite and polyvinyl alc. (PVA). Firstly, chem. composition and phys. characteristics of GFO (by GC/MS) and CP (by SEM and BET) were thoroughly characterized. PVA/CP xerogel was synthesized then and characterized by SEM, BET, TGA, and DSC techniques. Adsorption of the 12 GFO components on the CP and PVA/CP xerogel surface was investigated in different concentrations of GFO components. Both adsorbents showed concentration-independent and selective adsorption for GFO components. The selective adsorption index showed a direct relationship with polarity (δP) of the components and inversely correlated with their molar volume (Vm). Adsorption isotherms of the components were fitted by Langmuir, Freundlich, and Temkin equations. Maximum monolayer GFO adsorption on PVA/CP surface was equal to 231.93 mg g-1 compared to 198.73 mg g-1 for CP as an adsorbent. The maximum desorbed amount for each of the components was directly related to the Vm parameter and the weight percentage of each GFO component in the oil and inversely related to δP. Multilayer desorbed amount from PVA/CP xerogel particles (366.03 mg g-1) was less than that for CP particles (573.36 mg g-1) supporting PVA/CP for retaining GFO for longer periods.
