In the present study, alumina nanoparticles (nano-alumina) which were successfully fabricated by solvothermal method, characterized X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Transmission Electron Microscopy (TEM), and Brunauer⁻Emmett⁻Teller (BET) methods. The removal of cationic dye, Rhodamine B (RhB), through adsorption method using synthesized nano-alumina with surface modification anionic surfactant was also investigated. An surfactant, sodium dodecyl...
Silver nanoparticle (AgNP) has a wide range antibacterial effect and is extensively used in different aspects of medicine, food storage, household products, disinfectants, biomonitoring environmental remediation etc. In the present study, we examined growth inhibition engineered silver nanoparticles against bloom forming cyanobacterial M. aeruginosa strain. AgNPs were synthesized by chemical reduction method at room temperature UV–Vis spectroscopy, scanning electron microscopy (SEM),...
We investigated adsorption of anionic surfactants, sodium dodecyl sulfate (SDS) and tetradecyl (STS), onto alumina (Al 2 O 3 ) with large size in the present study. The effective conditions for SDS STS Al were systematically studied. γ -Al optimized found to be contact time 180 min, pH 4, 1 mM NaCl. Adsorption both beads increased an increase ionic strength, demonstrating that is controlled by electrostatic attraction between groups positively charged surface, as well hydrophobic...
An electro-Fenton system, which consists of a Pt gauze anode and commercial carbon felt cathode, is commonly employed to generate in situ hydrogen peroxide, hydroxyl radical regenerate ferrous catalyst for glyphosate degradation (a widely used herbicide Vietnam) aqueous solution. The absorbance measurements determine the concentration during electrolysis proved that was degraded by pseudo-first-order kinetic. influence pH, current density, initial content on mineralisation efficiency were...
X-ray diffraction, scanning electron microscopy and transmission showed that TiO2 particles synthesized by a sol–gel procedure exhibited uniform size about 16–20 nm. This nanopowder was deposited on porous quartz tube (D = 74 mm, L 418 deposit density ∼16.4 mg cm−2) through an intermediate adhesive polymethylmethacrylate layer to manufacture photocatalytic filter tube. A polypropylene pre-filter coated with nanosilver (particle ∼20 nm) prepared aqueous molecular solution method. An air...
The presence of herbicide is a concern for both human and ecological health. Glyphosate occasionally detected as water contaminants in agriculture areas where the used extensively. removal glyphosate synthetic solution using advanced oxidation process possible approach remediation contaminated waters. ability electrochemical degradation mineralization was investigated Ti/PbO2 anode. current intensity, treatment time, initial concentration pH are influent parameters on efficiency. An...
Extensive removal of 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) using titania (TiO2) nanoparticles by adsorption and photocatalysis with a surface coating cetyltrimethylammonium bromide (CTAB) is reported. The CTAB-coated TiO2 (CCTN) were characterized FT-IR, zeta-potential measurements, UV–vis diffuse reflectance spectroscopy (UV–vis-DRS). 2,4,5-T increased significantly after modification CTAB compared bare nanoparticles. Optimal parameters affecting found to be pH 4, CCTN dosage 10...
In the present study, we investigated removal of an emerging pesticide lindane from aqueous solution using synthesized aluminum hydroxide Al(OH)3 (bayerite) nanomaterials with surface modification by anionic surfactant sodium dodecyl sulfate (SDS). The nanoparticles were characterized X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET) and zeta potential. SDS-modified nano-aluminum (SMNAH) achieved up to...
Gastric cancer (GC) is the remaining concern of cancer-associated health burden. Valuable predictive and prognostic indicators support early diagnosis improve outcome. Immune escape inflammation are important hallmarks. The diagnostic value platelet-to-lymphocyte ratio (PLR) neutrophil-to-lymphocyte (NLR) was reported in some cancers. But these cheap convenient indexes far from clinical use. Thus, investigation alteration those index on GC needed to impose use clinic. study recruited...
The development of highly efficient and stable visible-light-driven photocatalysts for the removal herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) from water is still a challenge. In this work, Bi
Hollow TiO2 nanostructures have been fabricated by a facile self-templated hydrothermal synthesis without the assistance of any fluoride compound. The hollow with diameters approximately 2 μm are composed mesoporous shell walls 200 nm in thickness.
