Adsorption of 2-picoline and 3-Amino-2-picoline onto Kaolin and Organo-modified Kaolin
The adsorption of 2-picoline (PC) and 3-Amino-2-picoline (APC) onto kaolin and organomodified kaolin was investigated. Tetraethylamoniumiodide (TEAI) was used as modification reagent. The sorbent was characterized by FTIR, XRD, SEM and BET methods. The influence of various parameters like contact time, PH, adsorbent dose and initial concentration of PC and APC was studied. The adsorption kineti...
متن کاملAdsorption Equilibrium and Kinetics of Lead Ion onto Synthetic Ferrihydrites
Batch experiments were conducted to study the adsorption behaviors of lead ion (Pb2+) onto ferrihydrites prepared using three different procedures which were characterized by textural analysis (BET). The adsorption removal of Pb2+ by the three ferrihydrites (called FH-1, FH-2 and FH-3, respectively) were compared, and FH-3 shows fast adsorption kinetics as well as hig...
متن کاملRemoval of Toxic Pollutants from Aqueous Solutions by Adsorption onto Organo-kaolin
In this study, the adsorption of toxic pollutants onto cetyltrimethylammonium kaolin (CTAB-Kaolin) is investigated. The organo-kaolin is synthesized by exchanging cetyltrimethylammonium cations (CTAB) with inorganic ions on the surface of kaolin. The chemical analysis, the structural and textural properties of kaolin and CTAB-kaolin were investigated using elemental analysis, FTIR, SEM and adso...
متن کاملAdsorption of Lead from Aqueous Solution onto Untreated Orange Barks
Waste materials with no further treatment such as orange barks from commercial oranges may act as adsorbent for the removal of Pb. Batch kinetic and equilibrium experiments were conducted to study the effects of contact time, initial pH, adsorbent dose and initial concentration of lead. The results show that the equilibrium was achieved less than 30 min of contact time. Three adsorption isother...
متن کاملSpectroscopic study of ionic liquid adsorption from solution onto gold.
Gold was exposed to ethanol solutions containing 0.1 wt% 1-hexyl-3-methyl-imidazolium bis(trifluoromethanesulfonyl)imide (HMIM NTf2), an ionic liquid (IL). The resulting adsorbed layers were interrogated using X-ray photoelectron spectroscopy (XPS - both conventional and synchrotron-based) and spectroscopic ellipsometry. Ellipsometry indicated that the adsorbed layer thickness was smaller than ...
