Adsorption and Photocatalytic Properties of Surface-Modified TiO2 nanoparticles for Methyl Orange Removal from Aqueous Solutions
Titanium dioxide nanoparticles surface-modified by 5-sulfosalicylic acid 5-SA-TiO2 were prepared in ethanol by the chemisorption process. The effects of surface improvement on the photocatalytic degradation and adsorption of methyl orange MO were studied in a batch system by considering the various parameters, such as contact time, adsorbent dosage, pH, initial dye concentration and temperature...
متن کاملAdsorption of methyl mercaptan on surface modified activated carbon.
The influence of surface modification of activated carbon on the adsorption of methyl mercaptan in N(2) was investigated. The modification of the activated carbon was carried out by treatment with HNO(3)/H(2)SO(4) solutions, heat-treatment in Ar, and adsorption of cetylamine. Acid-treatment increased the adsorption of methyl mercaptan compared with the original activated carbon, and the adsorbe...
متن کاملAdsorption of Methyl orange dye from Water solutions by carboxylate group functionalized multi-walled Carbon nanotubes
The present study was carried out to investigate the potential of carboxylate group functionalized Multi-walled carbon nanotubes (MWCNT−COOH) adsorbent for the removal of Methyl orange (MO) textile dye from aqueous solutions. The effects of pH, shaking time and temperature on adsorption capacity were studied; the contact time to obtain equilibrium at 298 ˚K was fixed at 25 min. The effect of te...

متن کاملIRON-MODIFIED CARBON-COATED TiO2 FOR ADSORPTION AND DECOMPOSITION OF PHENOL IN WATER
Carbon-coated TiO2 catalysts were found to have high photocatalytic activity for photodecomposition of methylene blue in water, higher than TiO2 without carbon coating [1]. However, these catalysts used for phenol decomposition showed lower activity than TiO2 without carbon coating. Also lower adsorption capacity of phenol on carbon-coated TiO2 catalysts was noted by comparison with adsorption ...
