| dc.description.abstract | The increasing use of alternative waste activated carbon production ramped up this research project with the aim to develop new activated coals from coconut residue utilization, the banana and orange as precursor material, favoring the sustainability of the environment. Specific analyses were carried out and officers, noting the textural and chemical characteristics of these materials, since the literature does not describe the characteristics of activated carbon derived from the precursor material that will be used. First collected the fiber-to-dried coconut and banana and orange bagasse/cark for subsequent preparation of this material by impregnation with ZnCl2, chemical activation and performing a test for evaluating the efficiency of the coal. The results were an activated carbon with carbon mass fixed in all samples (coconut/banana = 25/75), (coconut/banana = 75/25), (coconut/orange = 75/25), showing efficiency in the reduction of pH, electric conductivity values and turbidity of the water. Therefore, the production of activated carbon from waste coconut, banana and orange presented, comparatively, the characteristics of activated coals ever produced for other waste and proved to be a viable alternative for the industry that has a vested interest in large-scale production, benefiting the industry and the environment. The activated carbon of banana and orange decreased the pH and electric conductivity; and the Orange was more effective in reducing turbidity in 98.4%. | eng |
