Impact of Flow Rate And Bed Height on the Fixed Bed Adsorption of Methylene Blue Dye on to Sphagnum Cymbifolium (Moss)
Objective: This work is aimed at expanding the field of application of natural biomass for the treatment of dye waste effluents. It is equally aimed at determining the dependency or otherwise of the effect of flow rate and bed height on the fixed bed adsorption of methylene blue dye onto Sphagnum cymbifolium (moss). Methods: The biomass was characterized by scanning electron microscopy (SEM) for the determination of the morphology of the biomass. The screened biomass samples were characterized at 1000X magnification, 500X magnification and 250X magnification respectively for their surface morphologies. This was done using a scanning electron microscope (FEI-inspect/OXFORD INSTRUMENTS-X-MAX), which was equipped with an energy dispersive x-ray (EDAX) spectrophotometer employed for the elemental composition analyses. It was equally characterized with Fourier transformed infrared spectroscopy (FTIR) before and after adsorption to ascertain the functional groups responsible for the adsorption. This was done using a Fourier Transformed Infrared (FTIR) spectrophotometer (Perkin Elmer, England) in the wavelength range of 350-4000nm.
Evaluation of Dye Bio-Sorption Properties of Sphagnum Cymbifolium (Moss) in Aqueous Solution by the Batch Process
Objective: One of the major objectives of this research work is to expand the field of application of natural biomass for the treatment of dye based industrial effluents. It is also aimed at studying the effect contact time, initial dye concentration, pH, temperature, dissolved salts on the bio-sorption properties of sphagnum cymbifolium(moss) on to methylene blue dye by the batch process. Methods: The biomass was characterized by scanning electron microscopy (SEM) in order to examine the surface morphology of the biomass. The screened biomass samples were characterized at 1000 x magnification, 500 x magnification and 200 x magnification for their surface morphologies, This was done using a scanning electron microscope (FEI – inspect/ OXFORD INSTRUMENTS – X- MAX), which was equipped with an energy dispersive X- ray (EDAX) spectrophotometer employed for elemental composition analysis. It was equally characterized with Fourier transformed infrared spectroscopy (FTIR) spectrophotometer (Perkin – Elmer, England) in the wavelength range of 350 – 4000nm.
