Synthesis and Surface Modification of Mesoporous Silicate SBA-15 for the Adsorption of Metal Ions
In this study surface modified SBA-15, coated with octadecyltrichlorosilane (C18), is considered as an alternative adsorbent for metal ions in water. The SBA-C18 was loaded with Bis(2,4,4-trimethylpentyl) phosphinic acid (cyanex 272) as the metal ion extractant. The adsorption characteristics of phosphinic acid loaded SBA-C18 were evaluated for Cu(II) and Zn(II) ions in aqueous solution. Adsorp...
متن کاملSeparation Of Gangue From Coal Based On Histogram Thresholding
Coal gangue is residual abandoned coal, produced after the pre-processing steps of mining. It is an amalgam of several unwanted substances. It is important to separate coal gangue from lump coal before fed to thermal power plants. In this paper, investigation on the fundamental characteristics of coal images and gangue images with digital image processing technology is proposed. The system dete...
متن کاملDegradation of trinitroglycerin (TNG) using zero-valent iron nanoparticles/nanosilica SBA-15 composite (ZVINs/SBA-15).
Trinitroglycerin (TNG) is an industrial chemical mostly known for its clinical use in treating angina and manufacturing dynamite. The wide manufacture and application of TNG has led to contamination of vast areas of soil and water. The present study describes degradation of TNG with zero-valent iron nanoparticles (ZVINs) in water either present alone or stabilized on nanostructured silica SBA-1...
متن کاملPost-synthesis deposition of V-zeolitic nanoparticles in SBA-15.
A post-synthesis deposition of vanadium silicalite-1 zeolite nanoparticles in the pores of SBA-15 results in a highly ordered hexagonal templated silica material with V-silicalite zeolitic plugs, giving rise to an increased crystallinity of the amorphous mesoporous walls.
متن کاملSynthesis, characterization and photocatalytic activity of CeO2-SBA-15
Mesoporous photocatalysts of CeO2/SBA-15 are prepared by two methods of direct synthesis as solvent-usage and solvent-free methods. In solvent-usage method, CeO2/SBA-15 is synthesized in acidic media. While, in solvent-free method, CeO2/SBA-15, has been prepared through the novel path of directly grind cerium salt into the as-prepared samples of SBA-15 occluded ...
