The Freundlich constant (n) was higher than 1 as an indication of the physical adsorption process. The Radlich-Peterson calculations obtained the higher R2 value which g constant near 1, a high similarity with Langmuir model. Temkin constant B1 was a positive indication of endothermic process. All calculations provided favorable results for the use of activated biocarbon for dye removing and possible for other organic substances.515-522openAccesscarbonmethylene blueeucalyptusesmetalstoxic materialspollutionadsorptionwater pollutionArtigo de periódico8810.4236/ajac.2017.88037https://orcid.org/0000-0002-7737-3732
