Adsorption of Methylene Blue from Aqueous Solution onto Polyathia longifolia Seeds - a Low-cost Adsorbent
J. Environ. Nanotechnol., Volume 8, No 2 (2019) pp. 28-32
Abstract
The preparation of activated carbon from Polyalthia longifolia seeds by various chemical methods have shown 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 samples was reviewed by Scanning electron microscopy and the surface functional groups were 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 investigated to assess the suitability of carbon as adsorbent. Results of the examination have indicated that the activated carbon prepared using Polyalthia longifolia by H2O infuse process followed by activation at 110 °C, yielded activated carbon with the highest surface area and more developed micro-, meso-, macro-porosity. The prepared Activated carbon can be used to remove methylene blue dye.
