Adsorption process is an important technique in separation processes, which is used in heavy metals removal from aqueous solution. Orange peel has been investigated for the adsorption of uranium ions from aqueous solution. The parameters of pH, contact time, initial uranium ion concentration, temperature and adsorbent dose have been investigated in batch experiments. The adsorption kinetics wer...

INTRODUCTION A pro-apoptotic effect of circulating mediators on renal tubular epithelial cells has been involved in the pathogenesis of sepsis-associated acute kidney injury (AKI). Adsorption techniques have been showed to efficiently remove inflammatory cytokines from plasma. The aim of this study was to evaluate the efficiency of the hydrophobic resin Amberchrom CG161 M to adsorb from septic ...

this paper presents the adsorption of phenol on granular activated carbon (gac) from nutrient medium suitable for roorganisms’ growth and also the subsequent biodegradation. two parameter langmuir and freundlich adsorption isotherm models were studied using large range of phenol concentration (50-1000 mg/l). in low range of phenol concentration (50-300 mg/l), correlation coefficient, normaliz...

Since the mid-1970s, a new process for plasma phrases became available which used membrane modules instead of centrifuge. Many patients suffering from severe diseases with a poor prognosis could be cured. The advantages of therapeutic aphaeresis with membrane modules are a complete separation of the corpuscular components from the plasma, an effective elimination of macromolecular substances an...

Adsorption has become an attractive method for the extraction and recovery of metals from wastewater effluents. This study involved fabrication mesoporous neat polyacrylonitrile (PAN) monoliths composite polymer PAN poly-4-vinylpyridine (P4VP) as adsorbents toxic elements (As(V), Cr(VI)) PGMs(Ru(III), Rh(III), Pd(II)) simulated solutions. Fabrication was conducted using non-solvent induced phas...

This study presents the adsorption performance indicator for the evaluation of thermal power plant CO2 capture on mesoporous graphene oxide/TiO2 nanocomposite. To begin, this adsorbent was synthesized and characterized using N2 adsorption-desorption measurements (BET and BJH methods), X-Ray Diffraction (XRD), Field Emission Scanning Electron Microsc...

Earlier computations on the work of separation of boundaries with adsorbed solute atmospheres are reconsidered in terms of reversible work cycles. Special attention is given to two limiting cases. These are the separation of a material interface under fully equilibrated conditions, for which the chemical potential of the adsorbed solute remains constant, and separation under constrained conditi...

For a multiproduct microalgal biorefinery, most of the cell components should be extracted and fractionated. This work investigates fractionation lipids from other (pigments, proteins, carbohydrates) using polymers IL solutions in aqueous two-phase systems (ATPS). The poorly migrated to phases ATPS were recovered (97% total fatty acids) third phase (interphase) formed between top bottom phases....
