“…This explained the high reddish colour in the natural clay as compared to the modified. The presence of a moderate amount of CaO could be attributed to the occurrence of carbonate such as calcite in the sediments, and there is no detectable amount of Na2O, which may suggest that the predominant clay mineral is a Ca-rich type [16].…”

In this study, Dijah-Monkin bentonite clay was modified with a cationic surfactant hexadecyltrimethylammonium bromide (HDTMA-Br) at the level of twice the cation exchange capacity (CEC). This process results in the development of hydrophobic organoclay with an improved adsorption capacity. The clay obtained from Zing LGA Taraba State, North-East Nigeria, was beneficiated and pulverised to a particle size of 125 µm. The modification was performed without acid activation to prevent damages to the clay’s crystal structure. The organoclay was characterised for chemical composition, functional groups, mineralogical and surface morphology using X-ray fluorescence (XRF), Fourier Transform Infrared (FTIR) spectroscopy, X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. The XRD showed an increase in the basal spacing from 15.681Å to 17.758 Å, while the XRF revealed a 5.35% concentration of Br on the modified clay, indicating successful intercalation. The FTIR spectra also revealed the appearance of symmetric and asymmetric stretching bands at 2847.7cm-1 and 2914.8cm-1, respectively, as a consequence of the modification, resulting in more sites for adsorption.

“…The X-Ray method was used to determine the chemical composition of bentonite, and the pH value of the biosorbent was determined by the zero-charge method. [11,12]. However, when it comes to Fe 2 O 3 content, the results obtained are lower than those (11.10 wt.…”

The effect of the initial concentration of Cr, Co, Cu, Ni, and Pb metal ions from multicomponent solutions on the sorption capacity of natural and acid activated bentonite was examined in this paper. The acid activation was performed by using hydrochloric and sulfuric acid at different concentrations. The results of adsorption research have shown that bentonite can be effectively used as an adsorbent for the removal of metal ions from multicomponent solutions. Acid activation of bentonite changes the structure and content of individual oxides, increases the porosity and the number of available spots for the adsorption process. For this reason, the bentonite removal efficiency increased after acid activation for all heavy metals tested. With increased acid concentration, the degree of bentonite adsorption increased, and sulfuric acid rather than chloric acid showed better results in removal efficiency.

“…Nigeria has been blessed with an abundance of bentonite reserves and this would greatly reduce the importation of specialized DFs and ingredients, if properly harnessed. It has been reported that all regions in Nigeria possess a significant bentonite clay deposit and the country's bentonite reserves are put at the region of 700MM metric tons and above [4] with Edo State (Mid-Western Nigeria) being the largest shareholder and boasting a reserve of about 70-80MM metric tons of bentonite clay [5,6]. In 2003, the Federal Government placed a restriction on FB importation so as to promote the use of the large local deposits [7].…”
