Adsorption of Methylene Blue from Aqueous Solution onto Polyathia Longifolia Seed as A Low Cost Adsorbent

The preparation of activated carbon from Polyalthia longifolia seed by various chemical methods shows excellent improvement in the surface characteristics. Surface morphology also plays a significant role in the adsorption properties along with surface functional groups. The morphology of the resulting sample was reviewed by scanning electron microscopy and the surface functional group was investigated by infrared spectroscopy techniques, physico-chemical characteristics such as bulk density, moisture content, ash content, matter soluble in water, soluble in acid, PH iodine number, conductivity, porosity, yield percentage and surface area have been carried out to assess the suitability of the carbon as adsorbent, results of this examination indicate that the activated carbon prepared using polyalthia longifolia by H2O infuse process followed by activation at 110oC and yield activated carbon with the highest surface area and more developed micro, meso, macro porosity. The Prepared Activated carbon is used to remove methylene blue dye.
