Abstract EN
The waste of palm branches (PB) was tested for its ability to remove chromium (VI) from aqueous solution by batch and column experiments.
Palm branches chemically modified with an oxidizing agent (sulphuric acid) then coated with chitosan and surfactant (hexadecyl trimethyl ammonium bromide surfactant, HDTMA), respectively, were carried out to improve the removal performance of PB.
The results of their Cr (VI) removal performances are pH dependent.
The adsorption data could be well interpreted by the Langmuir, Freundlich, and Flory-Huggins isotherm models.
The maximum adsorption capacity obtained from the Langmuir model for the chitosan coated oxidized palm branches is 55 mg/mg.
The adsorption process could be described by pseudo-second-order kinetic model.
The intraparticle diffusion study revealed that film diffusion might be involved.
The biosorbents were successfully regenerated using 1 M HCL solution.
