Abstract

Comercial activated carbon samples (A, B, C, and D) used in filters for the treatment of water were characterized and evaluated in the decontamination of heavy metals present in river water and in the elimination of coliform microorganisms. The carbon samples had microporous and mesoporous structures. Surface areas of between 705 and 906 m²/g were found. The carbon samples were amorphous and the presence of antibacterial agents such as Ag, Cl, Cu, and Si was detected. It was determined that for As and Pb. whose initial concentrations in contaminated water (water of the Tumbes river-Peni) were 56.7 and 224.0 μg/L, respectively, the percentage of adsorption was close to 100%. The relationship between point of zero charge pH of the activated carbons and pH of the river water during the experiments plays a determinant role in the adsorption of the analyzed elements. The antibacterial capacity was evaluated satisfactorily against the following strains of fecal gram negative bacteria: Escherichia coli (ATCC® 25922™), Salmonella typhimurium (ATCC® 14028™). and Shigella flexneri (ATCC® 12022™). This ability is based on the surface presence in the carbons of the mentioned antibacterial agents.
