There is a considerable need for the removal of colour from wastewater or effluents. Currently, several physical and chemical processes are used for dyes wastewater treatment. However, these processes are of high cost and not efficient for the treatment of wide range of wastewater. In this study, the waste fruit shell of Limonia Acidissima is used as a biosorbent. The powdered raw material and treated material of specific micron size is used for the removal of the methylene blue from aqueous solution. The applicability of this treated material and raw material as an adsorbent for organic pollutant removal was studied and optimum conditions were evaluated for efficient adsorption of methylene blue. The results show that the removal of dye by chemically treated material is effective than raw material at higher temperature. The percentage removal of dye is maximum at 350C for treated material and at 250C for raw material.
