| Abstract | ||||
| 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. | ||||
