Carbon dioxide from the biogas resulted in vinasse fermentation should be treated. One of methods that could reduce carbon was adsorption process. A chemical and physical process modify characteristic obtain activated as an adsorbent. Chemical activation using H2SO4 ranged 5% to 30%, pyrolysis at 400oC for 3 hours. The done by inserting 98.68% synthetic CO2 range 0.002 0.0058 L/min bottom colum...

we utilize isotherm models in contributing to scholarly knowledge in simple terms, to measure the forces or energy defining certain adsorption phenomenon. gas chromatography coupled with mass spectrophotometer detector (gcms) was utilized to measure equilibrium phase atrazine after adsorption onto shea nut shells (ss) acid derived activated carbon. data were fitted into the d-r and temkin isoth...

Nickel-based activated carbon was prepared from coconut shell activated carbon by electroless plating with palladium-free activation. The materials were characterized by scanning electron microscopy (SEM), X-ray energy dispersion spectroscopy (EDS), vibrating sample magnetometry (VSM), and vector network analyzer, respectively. The results show that the surface of the activated carbon was cover...

From application perspectives in adsorption, activated carbon fiber (ACF) is by far one of the most important carbon nanoporous materials to be considered. It has great advantages over other commercial porous storage materials. Activated carbon fiber (ACF) is a promising microporous material with a fiber shape and well-defined porous structure. In general, production of ACF can be commercially ...

INTRODUCTION With its large internal surface area, activated carbon has extraordinary adsorptive capabilities. It is employed in a wide range of applications, mostly as a purifying agent to remove trace quantities of undesirable species from gas or liquid phase as well as an economical medium to recover precious materials. The demand for activated carbon has been continuously increasing in the ...

Activated carbons are extremely versatile adsorbents for major industrial significance, especially for metal ions recovery from wastewaters. In this study, the activated carbon <span style="font-size: ...
