Abstract – In the present investigation, ipomoea carnea (besharam) plant bark powder is used as an adsorbent for the removal of chromium from aqueous solution. The equilibrium studies are carried out in a batch process, covering various process parameters such as agitation time, adsorbent dosage, initial chromium concentration, pH of the aqueous solution. Adsorption is an important process used for the removal of colour, odour, turbidity, metal ions and reduction of concentration of hazardous elements from aqueous solution. In adsorption, the solute present in dilute concentration in liquid or gas phase is extracted by contacting with suitable solid adsorbent so that the transfer of the component first takes place on the surface of solid and then into the pore of the solid. Adsorption behaviour is found to follow Freundlich and Langmuir isotherms.
