The use of Metal-Organic Frameworks (MOF) such as HKUST-1 in textiles is an alternative with regard to the development technologies that are increasingly seeking for functionalities, mainly fields health and hygiene, named biofunctional fabrics. However, application MOF under surface wool fiber can lead a low durability finish due its fixation. Thus, this project aims perform direct synthesis HKUST fiber, so product good washing be obtained. purpose study was incorporate metal-organic...
Silica-coated magnetite (Mag-Sil) was prepared by the co-precipitation method using sodium metasilicate under an inert atmosphere and a fine pH control. Cetyltrimethylammonium bromide (CTAB) adsorbed onto Mag-Sil aiming at decreasing natural hydrophilicity of silica surface, allowing study hydrophobic interaction with dodecylbenzenesulfonate (SDBS) to be carried out. presented low surface Brönsted acidity once point zero charge 7.5. The synthesized materials were characterized X-ray...
Abstract A static batch arrangement composed of anti-leak vials coupled to gas chromatography is proposed as a complementary system for performance assessment biogas desulfurization by adsorption. For testing, modified commercial activated carbon produced controlled thermal treatment in the presence iron(III) species improved desulfurization. The adsorbents showed superior hydrogen sulfide removal compared ordinary one. Pseudo-first-order, pseudo-second-order, and Bangham’s kinetic models...
The development of alternative methods biodiesel production still remains a major priority the biofuel industry. In this work, catalytic activity anhydrous and insoluble sodium tungstate (Na2WO4) its heterogenized form in silica (Na2WO4/SiO2) soybean oil methanolysis was studied. sol–gel process conducted by both acid basic routes, it observed that obtained solid catalysts Na2WO4/SiO2 presented different characteristics depending on conditions employed during their synthesis. afforded high...
This work proposes a novel technology for environmental remediation based on mesoporous silica spheres, which were successfully synthesized by the solvothermal method using cetyltrimethylammonium bromide as structuring agent. The adsorbent was designed to remove cationic dyes at strong acidic conditions. surface modified careful thermal treatment aiming condensation of silanol siloxane groups. characterized XRD, SEM, FTIR, N2 adsorption/desorption and equilibrium technique determine pHpzc....
Carbon nanoparticles have demonstrated their potential to develop materials with advanced applications in which luminescence and biocompatibility are exploited. In the search for sustainable methods produce these nanoparticles, natural carbon sources such as plant- animal-based products by-products been used. However, existing procedures still performed high temperature, pressure, long reaction times. This report proposes a method synthesize using tomato extract source, followed by...
