Resumen
The coconut fiber is produced in large quantities in Brazil, even though very small quantities are being used by some
industries, mainly cordage mats and handicrafts. An alternative usage would be the use of these fibers in biosorption of heavy metals
from aqueous solutions. This present study aimed to evaluate the potentiality of cadmium biosorption by coconut fiber. The coconut
fibers were used at kinetic analysis, influence of pH and adsorption isotherms were also carried out. It can be concluded that there is
great potential for the use of coconut fiber, and the optimum pH for adsorption was around 5.0. The adsorption kinetics is fast and equilibrium occurs within 120 min. The Langmuir isotherm was considered the most suitable to describe the experimental data.
