Resumen
This paper aims manufacturing a composite material using cellulosic matrix and carbono nanotubes for pollutants removal, as heavy metals (lead ions) and toxic gases (ammonium). First, composite manufacturing was idealized and processed, being optimized by Design Factorial, using Methylene Blue as pollutant. After optimization, multiwall carbon nanotubes (MWNT) were treat with nitric acid and adsorption analysis were made using paper itself, paper with MWCNT without any treatment and paper with MWCNT after acid treatment. All composites were characterized by SEM and all nanotubes were characterized using FTIR spectra. On lead adsorption, composites with MWCNT with acid treatment showed higher effective, around 250% higher than
paper itself. Although the percentage were not the same, they also showed to be better on ammonia adsorption.
