The present study synthesizes a novel adsorbent by coating Fe3O4 magnetic nanoparticles with amino functionalized mesoporous silica. The FTIR spectrums indicate that silica has been successfully coated on the surface of Fe3O4 and 3-aminopropyl tri methoxysilane compound have been grafted to the surface of silica-coated Fe3O4. The XRD analysis shows the presence of magnetite phase with cubic spi...

Herein, an ordered mesoporous carbon (OMC) material was prepared using a metal and halogen free method, its adsorptive potential for the cationic dye, ‘Methylene Blue’ (MB), investigated. Batch studies were carried out to determine influence of pH, dye concentration, adsorbent quantity, contact time on adsorption behaviour. Adsorption models based Langmuir, Freundlich, Temkin Dubinin-Radunkevic...

Further research is needed to try utilize calcium carbonate from chicken eggshells as an adsorbent. The use of adsorbent expected minimize the amount waste generation and reduce environmental pollution. This aims Eggshell powder was activated with 0.1 M HCl solution for 48 hours, then heated in oven at 150°C 30 minutes which enlarge pores, increase surface area, volume create new pores that wil...

The issue of excess slag waste generated in the iron and steel making industries has prompted investigations on use waste. objective this study is to develop an adsorbent capable capturing carbon dioxide (CO2) by using slag. A mesoporous CaO-Fe2O3-SiO2 (CFS) composite was synthesized from a dephosphorization slag, Pluronic 123 as template various acids, including formic acid (FA), hydrochloric ...

A meso-structured Al-MCM-41 material was impregnated with bromocresol green (BG) dye and then incorporated into a UV-Vis DRA spectroscopic instrument for the online detection of ammonia gas. The absorption response of the Al-MCM-41/BG ammonia sensing material was very sensitive at the optical absorption wavelength of 630 nm. A high linear correlation was achieved for ppmv and sub-ppmv levels of...
