Producción de Tela de Carbón Activado Para la Adsorción de Colorantes Azoicos y Trifenil-Metanicos.

Abstract

A fabric Activated carbon (TAC) was produced from a denim fabric through a chemical activation with H3PO4 at a concentration of 3 to 5% w / w followed by a pirosis In a (Thermo Scientific) tubular furnace atmosphere N2 nitrogen, activated carbon fabric Produced (TAC), was characterized: by determining UN pcc = 4.2, the Next UN analysis was obtained percentage of 47% fixed carbon 14% ash and moisture 11 %, evidenced by the DRX UN resemblance to coal More crystal and scanning microscopy Showing breaking fibers and carbonization, the (TAC) was used for adsorption of azo and trifenilmetanicos dyes, including: Crystal Violet, eosin, blue methylene, alizarin yellow, red Congo, bromocresol green and fucsina; FEATURING adsorption kinetics pseudo pseudo primer Order and Second paragraph These dyes frequently used in Laboratory Practice Environmental Microbiology. The adsorption isotherms UN behavior is evidence on the model of Langmuir, and chemo-adsorption typical of esta model with the lowest adsorption at pH close to the value of pcc (pH 5).
