Natural clay samples and calcined clay varieties treated with hydrochloric acid of various strengths were characterized by X-ray diffraction, positron annihilation spectroscopy, and IR spectroscopy. The specific surfaces and pore sizes were determined by nitrogen adsorption. The constituent phases of the ...
Modification of pulp chemistry and behavior was achieved by using kaolinite and Na-exchanged (swelling) smectite clay minerals, divalent metal ions (Ca(II)... A Mcfarlane,K Bremmell,J Addai-Mensah - 《Journal of Colloid & Interface Science》 被引量: 80发表: 2006年 ...
The Bentonite clay was modified with different concentrations of H2SO4, forms acid activated Bentonite clay under microwave irradiation. These acid activation catalysts were characterized by PXRD, SEM, BET, FT-IR and UV Visible spectral analysis. The morphology of the catalysts was characterized by ...

clay minerals show other activity which could positively affect animal welfare and productivity. However, each type of clay has its own specific binding capacity that can greatly vary according to its origin deposit and treatment. Moreover, clays may bind with not only noxious substances but also ...
Although there is no official corrective measure for the removal of phthalates from wine that contains them above the regulated limits, the use of nanomaterials synthesized by modification of clay minerals has been proposed for the removal of phthalates from wine at the lab level [91]. 9. Conc...
(69.78 ± 0.72%), while its clay and silt contents were only 24.74 ± 0.43% and 5.48 ± 0.32%, respectively. The investigated soil had a low OC content with a mean value of 2.49 ± 0.12%, and an EC mean value of 136.5 ± 0.5 µS/cm. The pH value of the soil is 6.47, ...
