Functionalization of activated carbons by HNO 3 treatment: Influence of phosphorus surface groups. Carbon , — Thakur, V. Vinu, A. Carboxy-mesoporous carbon and its excellent adsorption capability for proteins. The invention relates to a method for the one-step electrochemical regeneration of carbonaceous porous materials saturated with contaminants and, once the contaminant has been desorbed, its electrochemical transformation in solution. Said electrochemical method can also be used " in situ ", i. In addition, the invention can be used to increase the adsorption capacity of porous materials or the adsorption speed of contaminants, applying the phenomenon of "electroadsorption".
Preferably, the porous material is activated carbon. The percent regeneration efficiency RE is defined as the ratio of adsorption capacities of the sample and regenerated the original sample according to the following expression 1 : adsorptivity CA regenerate initial adsorption capacity CA where the adsorption capacities are measured in grams of phenol adsorbed per gram of CA. Example 1 : CA cathodic regeneration carried out in 0. What is claimed 1.
