Ultrasonication Impregnation Of Florisil With 1-octyl-3-methylimidazolium Tetrafluoroborate Used As An Adsorbent In The Removal Process Of Cs+ From Aqueous Solutions
The present paper presents the studies regarding the impregnation conditions through ultrasonication of 1-Octyl-3-methylimidazolium tetrafluoroborate- [OmimBF4] onto Florisil support in order to enhance the adsorption efficiency of the resulting adsorbent. The obtained Florisil impregnated with [Omi...

| description | The present paper presents the studies regarding the impregnation conditions through ultrasonication of 1-Octyl-3-methylimidazolium tetrafluoroborate- [OmimBF4] onto Florisil support in order to enhance the adsorption efficiency of the resulting adsorbent. The obtained Florisil impregnated with [OmimBF4] in various work conditions of ultrasonication was subjected to a complex characterization scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX) and Fourier transform infrared spectroscopy (FTIR) and was used as an adsorbent in the removal process of Cs+ from aqueous solutions. In order to obtain a stable and homogenous impregnation of the solid support surface which will achieve reproducible results in the adsorption processes, it is not necessary to increase the ultrasonication time, but we should use higher amplitude. The impregnated material obtained in the recommended conditions showed good adsorption performance in the removal process of Cs+ from aqueous solutions, developing a maximum adsorption capacity of 2.27 mg/g. |
