A magnetic Fe3O4/GO composite with potential for rapid solid-liquid separation through a magnetic field was synthesized using GO (graphene oxide) and Fe3O4 (ferriferous oxide). Characterization of Fe3O4/GO used scanning electron microscope (SEM), X-ray diffractometer (XRD), Fourier transform infrared spectrometer (FT-IR), and Vibrating Sample Magnetometer (VSM). A number of factors such as pH a...

BACKGROUND/AIMS Cytokines play important roles in the pathophysiology of systemic inflammatory response syndrome (SIRS) and sepsis. Therefore, some effective measures to remove cytokines from the bloodstream could be effective in the treatment of SIRS and sepsis. The aim of this study was to evaluate the cytokine adsorptive property of various adsorbents for the purpose of the development of ne...

A highly selective ligand exchange type adsorbent was developed for the removal of trace arsenic(V) (As(V)) and phosphate from water. This adsorbent was prepared by loading zirconium(IV) on monophosphonic acid resin. This adsorbent was able to remove toxic anions efficiently at wide pH ranges. However, low pH was preferable for maximum breakthrough capacity in an adsorption operation. The effec...

In this paper, a sensitive analytical method for four fungicides (procymidone, folpet, vinclozolin and ditalimfos) in environmental water and juice samples was developed by using magnetic solid-phase extraction (MSPE) with magnetic graphene nanocomposite (G-Fe3O4) as the adsorbent, followed by determination with gas chromatography and electron capture detection. Parameters such as the amount of...

In some part of the world, groundwater source can become unsafe for drinking due to the high concentration of fluoride ions [1]. The low cost and facile-produced adsorbent like palm stone could effectively removed fluoride ions through adsorption process. In this dataset, the influence of fluoride ion concentration, solution pH, adsorbent dosage, and contact time on fluoride ion adsorption by p...

Removal of cadmium from aqueous solution was studied; using platanus orientalis leaves (POL) and their ash in 2006 in Iran. Bach adsorption experiments were performed as a function of solute concentration, contact time, pH and ironic strength for the experiment. The effect of Ca , Mg , Na and K on adsorption was 2+ 2+ + then examined. The effect of this adsorbent on COD in aqueous solution show...

The aim of this study was to examine the use of polyamide 6 nanofibers as an adsorbent material for removal of dye on textile wastewater. Simulated wastewater of acid dye (namely Color Index Acid blue 41) was used for experiment test with concentration of 0.01, 0.02 and 0.03g/L. Two kinds of electrospun polyamide 6 nanofibrous membranes with weight per unit area respectively 1.0 and 2.9g/m2 wer...
