- Abstract
The Activated charcoal - AC is a carbonaceous material with high carbon content in its structure, it can be obtained from biomaterials such as: coconut shell, wood, bamboo, etc. Its pores are highly developed, have high adsorption capacity and have a microcrystalline form capable of selectively purifying liquids or gases. All the ACs have micro, meso and macro pores in their structure, but the relative proportion depends on the precursor and production process. In carrying out this work, activated carbon was produced from the charcoal of the babassu endocarp prepared via microwave radiation. The physical activation process took place in the atmosphere of CO2 via microwave radiation at room temperature 235 °C and activation time corresponding to 50 minutes. The characterizations of the AC were performed with the following techniques: Scanning electron microscopy - SEM; Surface area analysis - BET and porosity; Thermogravimetric analysis - TGA; Analyzes of methylene blue adsorption in the region UV-Vis. The data obtained in this research shows that babassu activated carbon produced at low temperatures and high activation time has better methylene blue adsorption characteristics than AC produced at high temperatures and less time.
