ADSORPTION OF p-NITROPHENOL IN THREE DIFFERENT ACTIVATED CARBONS AT DIFFERENT pH
Adsorption of p-Nitrophenol by three different activated carbons (F100, S.E.I. and B.D.H.) was carried out at 301 K and at controlled pH conditions. Two different adsorption models (Langmuir model and Freundlich model) were studied and compared. The adsorption capacity of the carbons depends on the Point of Zero Charge (PZC) and surface area of the carbons. Adsorption of the solute at higher pH...
متن کاملNew Insights on the Simultaneous Removal by Adsorption on Organoclays of Humic Acid and Phenol
The exploitation of thermal water as a heat source in houses and apartments (during winter) is a widely used alternative to natural gas. However, this type of water may contain organic contaminants, which must be removed before releasing the used water into rivers and lakes. Because of the presence of a wide range of pollutants (including phenolic compounds and humates), efficient, cheap remova...

متن کاملResonant Second Harmonic Generation Studies of p-Nitrophenol Adsorption at Condensed-Phase Interfaces
A comprehensive analysis of adsorption strength, average molecular orientation, and absolute molecular direction for p-nitrophenol at solid-air, solid-liquid, and liquid-air interfaces is obtained from the nearresonant optical second harmonic generation (SHG) from the interface. Perturbation theory calculations of the molecular nonlinear polarizability tensor elements using *-electron wave func...
متن کاملAdsorption of p-Nitrophenol by Surface Modified Carbons from Aqueous Solution
Adsorption isotherms of p-nitrophenol from its aqueous solutions on two samples of activated carbon fibres and two samples of granulated activated carbons have been determined in the concentration range 40~800 mg/L (ppm). The surface of these carbons was modified by oxidation with nitric acid and oxygen gas, and by degassing the carbon surface under vacuum at temperatures of 400, 650 and 950C. ...
