Abstract
Particles prepared from palm-fruit bunches have been used in batch tests for the adsorption of a basic dye (BR 18) over a range of initial dye concentrations with adsorbent particle sizes varying in the range 106–300 μm. The results revealed the potential of palm-bunch particles as low-cost adsorbents. The uptake of the basic dye was higher at smaller adsorbent particle sizes. The adsorption isotherm followed both the Langmuir and Freundlich models. Values of the separation factor, R, indicate favourable adsorption for the basic dye/palm-fruit bunch particle system, i.e., 0 < R < 1 and n > 1.
