This work investigates the competitive adsorption under dynamic and equilibrium conditions of ibuprofen (IBU) and amoxicillin (AMX), two widely consumed pharmaceuticals, on nanoporous carbons of different characteristics. Batch adsorption experiments of pure components in water and their binary mixtures were carried out to measure both adsorption equilibrium and kinetics, and dynamic tests were...
Heavy metal pollution is propagating throughout the world with the enlargement of industrial activities. The elimination of heavy metal ions from industrial wastewaters has drawn much attention because of the hazardous effects of the heavy metal ions on different organisms. According to these facts, poly (2, 2, 3, 3- tetracyanocyclopropyl) phenyl acryl...
The effect of sugarcane straw anion exchanger with Micro and Nanostructure scale as the adsorbent for contaminated water treatment was investigated. The effects of operating conditions such as adsorbent loading, initial anion concentration, pH and the presence of competitive ions on the adsorption performances were examined. Equilibrium time and pH and adsorbent dosage were 3h, 6 and 0.5g respe...
This work analyses 10 adsorption isotherm models applied to of Cr(III) and Cu(II) from binary solutions on electron-irradiated sheep wool (0-24-100) kGy. The results are compared with fitting the same adsorbates corresponding single solutions. competing cation significantly changes selected isotherms extent that even simultaneous in solution is rare. In case Cr(III), 4 favourable matches were f...
Abstract Adsorption is an important phenomenon widely used for the removal of contaminants. Several drinking water contaminants such as arsenic and fluoride, vanadium chromium, nickel, cadmium cobalt are found to coexist in nature multi-component mixtures water. Hence, modeling adsorption isotherms designing treatment systems has gained importance recently. However, review studies competitive l...
