Abstract Background and aims: Clean air is one of the basic needs for human health and well-being. However, along with economic growth and development, transportation, urbanization and energy consumption have also risen and provide many concerns such as air pollution, which require urgent and wide attention. Air pollution in the worldwide is considered as a risk factor for human health and one...
Cobalt molybdenum catalysts supported on novel activated carbon-HZSM-5 composites with different mass ratios were prepared by wet-impregnation method and pre-sulfided CS2. Characterization of these was done using X-ray powder diffraction, Fourier transform infrared spectroscopy, N2 adsorption-desorption, scanning electron microscope analytics. Their activity for the hydrodesulfurization reactio...
This study investigates the transformation of activated carbon (AC) powder, derived from polyethylene terephthalate (PET) through pyrolysis, into a specific type short cylindrical carbon. carbon-to-carbon (C-C) was completed by annealing AC powder in co-gas atmosphere He and CO2. produces low-porous, amorphous, micro rods (MCR) micron size. It is suggested that so-far unknown growth mechanism o...
Six carbon powders with varied surface areas and porosities were used to store and release acetaminophen (ACT). A 10 mg/mL solution of acetaminophen in phosphate buffer solution (pH = 7.0) at 25 ̊C with exposure to carbon powder for 72 hours was used to drive the maximum loading of acetaminophen into the powders. Carboxen 1012 (BET surface area of 1500 m/g) powder exhibited the greatest maximum ...
In this research, TiAl/Al2O3 composite was synthesized from mechanically activated TiO2-Al powder mixtures using microwave heating.The initial powder mixtures were mechanically activated and pressed into cylindrical tablets and then heated in a microwave oven. The effect of different amounts of excess Al and microwave susceptor material (SiC or graphite) on the ignition time and the result...
Introduction: There are different methods for removal of cadmium from aqueous solutions. Adsorption based methods are among the bests. One of the most important aspects for adsorption techniques is the availability of an accessible and economical adsorbent. This study aims to investigate cadmium removal from aqueous solutions by walnuts shell waste. Materials and Methods: Walnut Shell (WS) was...
the objective of this study was to assess the adsorption potential of activated carbon (ac) asan adsorbent for the removal of murexide (mu) from aqueous solutions. the influence of variablesparameters including ph, amount of adsorbent, sieve size of adsorbent, temperature and contact timeon mu removal was studied. following optimization of variables, the relation between concentrations ofdye re...
