Organometallic [Fe3O(OOCC6H5)6(H2O)3](NO3) as intercalant of bentonite

Abstract

Intercalation of organometalic compounds [Fe₃O(OOCC₆H₅)₆(H₂O)](NO₃)∙nH₂O on bentonite by weight ratio of bentonite:organometallic  (1 : 1); (1 : 2); (1 : 3); and (1 : 4) has been carried out. The intercalation bentonite was characterized using FT-IR spectrophotometer, XRD and XRF anayses. Characterization using FT-IR spectrophotometer showed higher intensity of peak wavenumber  at 470.6 cm^-1 for Fe₃-O vibration on the ratio (1 : 3). While XRD characterization showed the shift of diffraction angle of 2θ was 5.2° and has bacal spacing of 16.8 Ǻ. In the XRF characterization, the intercalation process of organometalic compounds [Fe₃O(OOCC₆H₅)₆(H₂O)](NO₃)∙nH₂O on bentonite was occurred optimally with percentage of metal oxide reached 71.75 %.
