Abstract
A biocarbon after activation process showed the removal percentage of 92% of
methylene blue in solution, the equilibrium parameter???RL value was in the
interval from 0 to 1, with 46% of surface coverage degree. 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.
