Abstract
Cymbopogon flexuosus (lemon grass) cultivated by farmers for fragrance, oils and folk medicine remediates/ accumulates highly toxic As(III) originating from geological deposits as well as anthropogenic activities. Cympobogon flexuosus contains citral, geraniol, isoneral in addition to several other bioactive compounds widely used for anticancer, antioxidant and antimicrobial properties. Insertion of arsenic in the food chain of human being has become a potential threat to the civilization these days. More than 10 million people of Bihar especially on or near the Gangetic Plain of Bhagalpur district in Bihar are suffering from the effects of arsenic on their body. Activated charcoal has already been reported for the adsorption of arsenic but due to its less efficiency in reusability, bentonite had been used as adsorbent in our previous work. Now, in our present work, Cympobogon flexuosus, a naturally occurring biomass, has been found to act as efficient adsorbent of arsenic. Several parameters such as pH, concentration, dosage have been highlighted in the present work. With increased doses of Cympobogon flexuosus biomass, desorption of As(III) takes place to some extent in the pH range 6.7 – 7.4. The maximum removal efficiency is 52.17% for 2g biomass powder up to 1 hour. The Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) has used for analysis of As(III). Thus, the kinetic study of uptake of arsenic by lemon grass has been done. The land being used for cultivation of lemon grass should contain arsenic and toxic elements well below the permissible limit.
Keywords: ICP-AES, Cymbopogonflexuosus, Kinetics, Bioactive, As(III).
