Introduction: Sodium bentonite and kaolin are respectively the montmorillonite and kandite
group of clays. Clay has important aspects of recycling plastic wastes as a catalyst. This study explains
the Fourier Transform Infrared, X-Ray Fluorescence and X-Ray Diffraction Characterization of commercially
available sodium bentonite clay and kaolin clay.
Materials and Methods: Kaolin has been used as a catalyst for an alteration of plastic wastes in-to useful
hydrocarbons but sodium bentonite has limited exploration. The functional groups of aluminum
monoxide, a1uminium hydroxide, and silicon monoxide were explored by Fourier Transform Infrared.
The main elements of kaolin and sodium bentonite, silica, aluminum oxide, potassium oxide, ferric oxide,
and titanium dioxide were found the difference of 7.33%, 23.09%, 0.55%, 11.40%, and 1.35% respectively
with rest of impurities identified by X-Ray Fluorescence.
Results and Discussion: The mineral phase in the presence of chlorite, cristobalite, halloysite, and
quartz of kaolin clay was identified by X-Ray Diffraction. Special peaks of kaolin and sodium bentonite
were obtained through X-Ray Diffraction and Fourier Transform Infrared spectra. The maximum
average crystalline sizes for kaolin and sodium bentonite are 42.47 nm and 26.55 nm respectively.
Conclusion: Compound class of alcohols and phenols have been traced in-between absorption 3620 cm-1
to 3697 cm-1 of O-H stretching for both samples and Si-O-H stretching was found for sodium bentonite
at 3695.17 cm-1. Sodium bentonite shows better acceptance of performance characteristics as a catalyst.
The experimental study also explains the comparative analysis of kaolin clay and sodium bentonite clay
useful for thermo-catalytic waste valorization.
