Bare palm fibre was investigated for its ability to perform as a suitable sorbent for methylene
blue dye from an aqueous solution. The effect of sorbent dose and temperature was investigated
using a batch sorption technique. The results revealed the potential of palm fibre, an agricultural
waste, as a low-cost sorbent for the dye examined. The isotherm data were closely fitted to the
Langmuir and Frendlich equations and the dye sorption capacity of palm increased as the sorbent
dose decreased. Maximum saturated monolayer sorption capacity of bare palm branches for
methylene blue dye was investigated. Reaction parameters such as change in particle size of the
sorbent material, sorbent mass, air flow rate, initial dye concentration and the medium temperature
were also evaluated. In addition, relationships between sorbent dose and Langmuir; Frendlich
constants were developed and are presented. The principal conclusions of the study are that the
reaction follows the pseudo first order reaction kinetics.
