Removal of as(Iii) with (cynodon dactylon) green dub and orange peel from aqueous medium

Abstract

In the present study,Cynodondactylon(green dub) and orange peel powder have been utilized for remediation of As(III) ion from an aqueous medium. Different weights of Cynodondactylon have been treated with 2ppm As(III) solution up to a fixed time interval and again fixed weight of Cynodondactylon has been treated up to different intervals of time at a pH range of 2-6.5. Similar experiments have been repeated with orange peel powder at different pH values to know the adsorption isotherm, remediation efficiency, and adsorption rate. Results show that percentage removal in 30 minutes is 99.5% and agitation time for equilibrium is 30 minutes, with orange peel powder whereas maximum percentage removal with Cynodondactylon is 98.5% at pH 2. Thus orange peel and Cynodondactylon both could be used as a potential adsorbent for removal As(III) from an aqueous medium.
