... which leads during filtration to constant pressure, to a strong and continuous decrease of the permeate flux. On the other hand, coagulation and adsorption make it possible to removal the colloidal fraction, which plays a significant role in membrane fouling. We considered the treatment of primar ...

The adsorption of C. I. Reactive Red 120 (RR120) on activated oil palm ash (AOPA) was studied in a batch system. The adsorption studies were carried out at different initial dye concentrations (50–600 mg L–1), solution pH (2–12) and temperature (30, 40 and 508C). Th ...

... with water were in very good agreement. For glycerol and α-bromonaphthalene, dynamic advancing contact angles were sometimes different. Protein adsorption on polyethersulfone (PES) membrane was well evidenced whatever the solvent and closely related to the drying procedure. The efficiency of ...

... bisphenol A was recorded, while under the same condition, the removal efficiency of sulfamethoxazole was only about 50%. Both biodegradation and adsorption to the sludge were thought to be responsible for the removal of bisphenol A, which is a relatively hydrophobic organic compound. In contrast, th ...

A continuous adsorption study in a fixed-bed column was carried out by using phoenix tree leaf powder as an adsorbent for the removal of methylene blue (MB) from aqueou ...

... clearly showed that P4VP was adsorbed on bentonite. The good efficiency in removing chromium ions from acidic solutions was demonstrated by adsorption kinetics. Freundlich and Langmuir isotherm models were used to determine adsorption capacity of Bf, Bf0.06 and Bf0.3 composites at 25°C and a ...

The objective of this study was to investigate the removal of phenol from aqueous solution by using acid activated red mud in batch adsorption experiments. The study was carried out as functions of pH, contact time, activated red mud dosage and initial phenol concentration. It was foun ...

... all of them were in good agreement with the experimental data except Redlich-Peterson. The results indicate that acidic pH (1.5) supported the adsorption of DY-12 on activated carbon developed from orange peel. Furthermore, adsorption kinetics of DY-12 was studied and the rate of sorption was foun ...

... as a function of pH in the presence of various electrolytes such as, LiCl, NaCl, KCl, Cu(NO3)2, CaCl2, Pb(NO3)2, AlCl3 and Fe(NO3)3 and then, the adsorption of Cu(II) ion onto sepiolite from aqueous solutions as a function of pH, ionic strength and temperature. We found that (1) zeta potential o ...
