Silica nanoparticles separation from water: aggregation by cetyltrimethylammonium bromide (CTAB).
Nanoparticles will inevitably be found in industrial and domestic wastes in the near future and as a consequence soon in water resources. Due to their ultra-small size, nanoparticles may not only have new hazards for environment and human health, but also cause low separation efficiency by classical water treatments processes. Thus, it would be an important challenge to develop a specific treat...
متن کاملProcessing Of Mesoporous Hydroxyapatite Using Cetyltrimethylammonium Bromide (CTAB) As A Porogen And Its Characterization
The present research attempt consists in the development of mesoporous hydroxyapatite using inexpensive ingredients using cetyltrimethylammonium bromide (CTAB) as template through a chemical-based hydrothermal method. Wide angle X-ray diffraction (XRD) reveals the formation of pure single-phased hydroxyapatite particles. Fourier transform infrared absorption spectroscopy (FTIR) and electron dif...
متن کاملPhase behavior of concentrated aqueous solutions of cetyltrimethylammonium bromide (CTAB) and sodium hydroxy naphthoate (SHN).
We have characterized the phase behavior of mixtures of the cationic surfactant cetyltrimethylammonium bromide (CTAB) and the organic salt 3-sodium-2-hydroxy naphthoate (SHN) over a wide range of surfactant concentrations using polarizing optical microscopy and X-ray diffraction. A variety of liquid crystalline phases, such as hexagonal, lamellar with and without curvature defects, and nematic,...
متن کاملEffective harvesting of microalgae by coagulation–flotation
This study developed a coagulation-flotation process for microalgae Chlorella sp. XJ-445 harvesting, which was composed of algal surface modification by combined use of Al3+ and cetyltrimethylammonium bromide (CTAB) and followed dispersed bubble flotation. Dissolved organic matter (DOM) in the medium was firstly characterized and mainly consisted of hydrophilic low molecular weight molecules. T...
متن کاملElectrophoretic properties of complexes between DNA and the cationic surfactant cetyltrimethylammonium bromide.
We use agarose gel electrophoresis to characterize how the monovalent catioinic surfactant cetyltrimethylammonium bromide (CTAB) compacts double-stranded DNA, which is detected as a reduction in electrophoretic DNA velocity. The velocity reaches a plateau at a ratio R = 1.8 of CTAB to DNA-phosphate charges, i.e., above the neutralization point, and the complexes retain a net negative charge at ...
