Low cost adsorbent prepared from Raphia hookerie fruit epicarp was used for RhB removal.
- ss="label">•
Optimum adsorption was obtained at pH 3.
- ss="label">•
Adsorption process fits the Freundlich isotherm and Pseudo second order kinetics model.
- ss="label">•
Maximum monolayer adsorption capacity obtained 666.67 mg/g.
- ss="label">•
RhB was found stable on the surface of the adsorbents thus desorption efficiency was less 25%.
