Novel Material Obtained from the Gasification Residues of Candiota Mine’s Coal for Cationic Dye Adsorption

This work aims to prepare and characterize the unburned carbon obtained from gasification residues evaluate its application as an adsorbent for removal of textile dye contaminants. The results physical chemical properties showed a specific mass 2.05 g/cm3, surface area 23.983 g/cm2, diameter pore volume 0.844 nm 2.262 cm3/g, respectively. These properties, along with point zero charge bonds present on surface, favored adsorption cationic dyes. great potential methylene blue, crystal violet, basic fuchsin if compared bromocresol green, indigo carmine. maximum values blue were up 99% kinetic was faster at beginning process, reaching equilibrium in less than 5 min. through isotherms capacity 333.33 476.19 mg/g, temperature 291 328 K, satisfactory that use is cost-effective eco-friendly alternative reusing residue also contributes decontamination watercourses.
