Lignocellulosic materials have been used as bioadsorbents for contaminants removal from industrial effluents due to their physical-chemical properties, renewable source, low-cost and efficiency that make them competitive commercial activated carbon. The objective of this work is develop an efficient low cost bioadsorbent reusing the cashew nut shell (Anarcadium accidentale L), CNS, metal ions (...

In this study, ZnO/g-C3N4 nanocomposites were prepared via a physical mixing-calcination process for improved degradation of dyes under visible light irradiation. The BET surface area, pore volume, crystal size, and pHpzc the composite 3.9 m2/g, 0.034 cm3/g, 18.1 nm, 7.7, respectively. Although morphology was very different from that pure g-C3N4, their average sizes similar. Eg (3.195 eV) sligh...

Abstract. This work deals with the synthesis of nanoparticles iron-potassium diphosphate, KFeP2O7, implanted on activated carbon produced from corncob debris. The chemical composition and structure carbon/potassium-iron diphosphate (AC/KFP) composite was analyzed by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) Transmission (TEM). Complementary tests were conducted to determine su...

zirconium dioxide, commonly known as zirconia, is an interesting material and is receiving growing attention due to its excellent mechanical properties. the solid was characterized for surface area measurements, scanningelectron microscopy (sem), energy dispersive x-ray diffractometry (edx) and potentiometric titrations. surface titrations were carried out at the temperature range 303 to 323k i...

<p>In the present study, adsorption experiments were carried out to investigate removal of rhodamine B from an aqueous solution using chemically activated carbon corn cobs, a cheaper adsorbent. The characteristics determined X-ray diffraction, SEM, iodine number, pHpzc, and Boehm titration method. results show that prepared is amorphous, microporous, generally acidic on surface. kinetic s...

Background: Among different pollutants released into the environment, dyes are considered as one of the most dangerous contaminants. In recent years, magnetic nanomaterials have attracted much attention for their dye removal capacity. The aim of this study was to explore the adsorption kinetics of an anionic dye (Reactive Orange 13 (RO)) by NiFe2O4 nanoparticles (NiFe2O4 NPs) under various cond...

In the present work, adsorption mechanism and capacity of MWCNTs/CoFe2O4 nanocomposite as an adsorbent were investigated. Levofloxacin (LFX), a widely used antibiotic, was selected hazardous model contaminant in aqueous solutions. The surface inner characterization obtained via SEM/TEM, XRD, BET/BJH, pHPZC. These analyses indicated that possess excellent pore characteristics, e.g., specific are...

NiFe2O4 nanoparticles had been successfully synthesized by solution combustion method using urea fuel (organic precursor). The were characterized X-ray diffraction (XRD), Scanning electron microscopy-Electron Dispersive Spectroscopy (SEM-EDs), Transmission Electron Microscopy (TEM), Fourier Transform Infra-Red (FTIR), Vibrating Sample Magnetometer (VSM), UV-Vis Diffuse Reflectance (UV-Vis DRS),...

Vinasse was successfully utilized to synthesize carbon–silica composite with a low-cost silica source available in Thailand (sodium silicate, Na2SiO3) and most commonly used source, tetraethyl orthosilicate (TEOS). The composites were prepared by simple one-step sol–gel process varying the vinasse (as carbon source) (Na2SiO3 or TEOS) weight ratio. resulting characterized N2 adsorption, moisture...
