In the first, cadmium selenide nanoparticles loaded on activated carbon (CdSe-NP-AC) has been synthesized. Then, this new adsorbent successfully has been applied for the removal of fluoride from aqueous solution in batch studies, while the effect of various experimental parameters like initial pH, contact time and temperature on its removal percentage was examined by one at a time optimization ...

the adsorption processes of amlodipine onto hydrophilic carbon nanoparticles (emperor 2000tm) are investigated. the significant increase in voltammetric responses for pre-adsorbed amlodipine compared with those for solution confirms high affinity of amlodipine to carbon nanoparticles (possibly due to π-π stacking interaction between aromatic rings of amlodipine and surface-sulfonated carbon nan...

in this work, sol-gel method was used tosynthesize titanium dioxide nanoparticles (tio2). the tio2nanoparticles was characterized by scanning electron microscopy (sem), x-ray diffraction (xrd) and bet technique.the tio2 and coumarin derivative (7-(1,3-dithiolan-2-yl)-9, 10-dihydroxy-6h-benzofuro [3,2-c] chromen-6-on) were incorporated in a graphite composite electrode. the resulting modified el...

This paper presents a systematic study of the surface chemistry, porous texture and adsorptive characteristics of prepared new activated carbon using Persian mesquite grain. Several techniques and methodologies such as, proximate analysis, N2 adsorption–desorption isotherms, scanning electron microscope (SEM), Fourier transform infrared spectroscopy(FT-IR), X-ray Diffraction (XRD), X-ray photoe...

in this study, zno nanoparticles were loaded on activated carbon prepared from almond shell (zno-np-ac). then, this novel material applied as an efficient adsorbent for the ultrasonic assisted simultaneous removal of basic blue 41(bb41) and basic red 46 (br46) in binary solution.  the efficiency of proposed activated carbon was enhanced by acid treatment and subsequent modification by physical ...

A bioreactor refers to any manufactured or engineered device that supports a biologically active environment. These kinds of reactors are designed to treat wastewater treatment. Volumetric mass transfer coefficient and the effect of superficial gas velocity, as the most important operational factor on hydrodynamics, in three-phase airlift reactors are investigated in this study. The experiments...

The inhalation of combustion-derived nanoparticles leads to adverse health effects in the airways. In this context the induction of membrane-coupled signalling is considered as causative for changes in tissue homeostasis and pro-inflammatory reactions. The identification of these molecular cell reactions allowed to seek for strategies which interfere with these adverse effects. In the current s...

A new activated carbon was produced from pulp and paper mill sludge as a low cost precursor via chemical activation by zinc chloride. The activated carbon was successfully used for the adsorption of phenol and two of its derivatives, i.e. 2-chlorophenol and 4-nitrophenol from aqueous solutions. The characterization of the prepared activated carbon demonstrated high textural properties for the s...
