The influence of the activated carbon post-treatment on the phenolic
Cansado, Isabel P. P.; Mourão, Paulo A. M.; Falcão, Ana I.; Ribeiro Carrott, M . Manuela L.; Carrott, Peter J. M.The aim of this research was to investigate how post treatment modification, such as those with sodium hydroxide or urea, can influence the capacity of activated carbon (AC) for phenolic compounds removal from liquid media. The ACs modification was performed using urea impregnation followed by pyrolysis at high temperature. With all ACs used, this treatment induced a pore volume increase, a mean pore size broad...
On the use of ethanol for evaluating microporosity of activated carbons prepare...
Carrott, Peter J. M.; Cansado, Isabel P. P.; Mourão, Paulo A. M.; Ribeiro Carrott, M. Manuela; Louro, Nélio D. B.; Albiniak, A.; Broniek, E.Microporous activated carbons prepared by KOH chemical activation or steam activation from lignite were characterised by adsorption of N2 at 77 K and CO2 at 298 K. Subsequently, the adsorption of ethanol was carried out and complemented by adsorption of benzene and cyclohexane. The isotherm analysis included application of the αs method using ethanol reference data obtained here by also studying non-porous carb...

Cansado, Isabel P. P.; Mourão, Paulo A. M.; Carrott, Peter J. M.; Carrott, Manuela L. R.The specific application of activated carbons (AC) as adsorbents for gases and vapours depends on the properties of pollutants to be removed, but the performance of the AC depends on various properties. If their porosity is the main parameter in gas adsorption, the chemical nature of their surface plays a significant role in liquid phase interactions and in their usefulness as catalyst support materials. Of par...
Activated Carbon Post Treatment - Influence on Phenolic Compounds Removal
Cansado, Isabel P. P.; Mourão, Paulo A. M.; Falcão, Ana I.; Ribeiro Carrott, M. Manuela; Carrott, Peter J. M.● AC preparation from different precursors and their modification / optimisation with sodium hydroxide and urea to improve the adsorption capacities for phenolic compounds from the liquid phase. ● Comparative study of the influence of textural and chemical parameters of AC on the liquid phase adsorption.

Modification and Optimization of Activated Carbons for Phenolic Compounds Removal
Cansado, Isabel P. P.; Mourão, Paulo A. M.; Ribeiro Carrott, M. Manuela; Carrott, Peter J. M.Phenols are generally considered to be one of the important organic pollutants discharged into the environment causing unpleasant taste and odour of drinking water. Development of inexpensive adsorbents from industrial wastes for the treatment of wastewaters is an important area in environmental sciences. For the phenolic compounds removal, it appears that the pH of the solution, the real surface area of the so...
Modification and Optimization of Activated Carbons for Phenolic
Cansado, Isabel P. P.; Mourão, Paulo A. M.; Falcão, Ana I.; Ribeiro Carrott, M. Manuela; Carrott, Peter J. M.Phenolic compounds are generally considered to be one of the important organic pollutants discharged into the environment causing unpleasant taste and odour of drinking water [1,2]. So, removal of phenolics compounds from industrial effluents is required before sewage disposal. The development of inexpensive adsorbents from industrial wastes for the treatment of wastewaters is an important area in environmental...
