Characterization of water commercial filters based on activated carbon for water treatment of the Tumbes river – Peru
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 structure...
