Hemp-based materials have been recently proposed as adsorbents for metals present in aqueous solutions using adsorption-oriented processes. This study aims to reveal the adsorption mechanism of prepared from hemp shives co-products industry, namely sodium carbonate-activated (SHI-C) and polycarboxylic agent-grafted (SHI-BTCA) shives. The interactions between copper two hemp-based were character...

Nowadays, nano mineral modified biochars show a promising adsorption capacity for pollutants removals by combining the advantages of porous structure biochar and unique property minerals. In this work, nano-zinc oxide doped scrap tire derived activated carbon (nZnO-STAC) was synthesized wetness impregnation method. Equilibrium data were analyzed using Langmuir Freundlich isotherm models while k...

Zero-valent iron nano-particle (nZVI) was modified with Spondias mombin (Sm) leaves extract (Sm-nZVI) for the removal of total petroleum hydrocarbons (TPH), hydrocarbon content (THC), and polycyclic aromatic (PAHs) from contaminated soil. Advanced analytical tools such as Fourier Transform Infra-Red (FT-IR) Spectrophotometer, Scanning Electron Microscope(SEM) X-ray diffractometer (XRD) were use...

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 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...
