ABSTRACT

Today's world is burdened with the need for potable water even with the numerous water bodies that exist. Among several other techniques, adsorption has become widely used for the removal of heavy metal ions and dyes from aqueous solution and numerous adsorbents for water treatment have therefore been prepared over the years. Ricinus communis effectively treat water by adsorption of both heavy metal ion and dyes from aqueous solutions. Some of these RC – when modified with chemicals – also have the abilityto efficiently remove heavy metal ion and dyes from water. Ricinus communis. Have higher adsorption capacityand better life cycles, therefore it shows an excellent potential in adsorption process. This article reviews the various Ricinus communis carbon that have been prepared recently and used as adsorbents in the removal of heavy metal ion and dyes from aqueous solutions. A special focus is placed on ricinus communis that are not only interesting from an academic point of view but also effectively reduce the concentration of pollutants in water.

Keywords: Adsorption, Ricinus communis carbon, Heavy metal & Dyes, Isotherms, Kinetic models.
