Adsorption Removal of Humic Acid from Water Using a Modified Algerian Bentonite
In this study, the main objective is the preparation and the characterization of a modified Algerian bentonite based adsorbent by intercalation with hexadecyltrimethylammonium bromide (HDTMA). Natural and modified bentonites were characterized using thermogravimetric analysis (TGA), X-ray diffraction (XRD) and infrared spectroscopy (FTIR). The X-ray results indicate that the geometry of the int...
متن کاملThe effect of humic acid adsorption on pH-dependent surface charging and aggregation of magnetite nanoparticles.
The pH-dependent adsorption of humic acid (HA) on magnetite and its effect on the surface charging and the aggregation of oxide particles were investigated. HA was extracted from brown coal. Synthetic magnetite was prepared by alkaline hydrolysis of iron(II) and iron(III) salts. The pH-dependent particle charge and aggregation, and coagulation kinetics at pH approximately 4 were measured by las...
متن کاملEffect of Humic Acid on the Selenite Adsorption onto Hematite
In the present study, we investigated the adsorption of selenite [Se(IV)] onto hematite, which usually exists in soils and rocks, focusing on the effect of humic acid. The selenite adsorption onto hematite varied with the contact time, finally reaching an equilibrium state in 5 hours. The result was in good agreement with the Parabolic diffusion equation (R 2 = 0.97). The adsorption with differ...
متن کاملEffect of Humic Acid on As Redox Transformation and Kinetic Adsorption onto Iron Oxide Based Adsorbent (IBA)
Due to the importance of adsorption kinetics and redox transformation of arsenic (As) during the adsorption process, the present study elucidated natural organic matter (NOM) effects on As adsorption-desorption kinetics and speciation transformation. The experimental procedures were conducted by examining interactions of arsenate and arsenite with different concentrations of humic acid (HA) as ...
متن کاملdetermination of optimum exposure time and ph for dye adsorption using an adsorbent made of sewage sludge
in this research feasibility study of using sewage sludge as an adsorbent for the removal of acidblue 25 dye was carried out. sewage sludge was first dried in an oven at 105° c for 24 hours. then the driedsludge was washed with hcl (98%) for two hours and then with distilled water to a ph of approximatelyneutral. then, it was carbonated and activated in a nitrogen-based electric furnace at 600c...
