Eichhornia and Ipomoea: Efficient phytoremediators of manganese
Year: 2014
Type: article
Abstract: Phytoremediation uses plants to remove pollutants from the environment. The content of heavy metals in the biosphere has been increasing over the past hundred years due to the economic activity of man. Manganese is one of the heavy metals which is toxic but then too necessary in trace amounts for all living organisms. However accumulation of this heavy metal is not ignorable. To maintain the balance of manganese in the environment phytoremediation of manganese is the most cost effective method. Leaves of two aquatic plant species viz. Eichhornia crassipes and Ipomoea aquatica were used as research tool for removal of manganese ions. The removal is dependent on the rate of adsorption by the leaves. Filtrate of leaves was used for various chemical tests and estimation of Mn by Ammoniumpersulphate method and volumetric analysis. Eichhornia gives better results as compared to Ipomoea. This was due to the increase in the adsorption capacity at higher dose of adsorbent. The removal of Mn ions from aqueous solutions using powder of different waste materials viz., Ipomoea leaves and water hyacinth was found to be increased on adsorbent dosage, initial concentration of sorbate, pH and contact time. As far as contact time is concerned Ipomoea showed better results for largest removal of manganese ions in comparison to Eichhornia.
