Removal of Methyl Orange from Aqueous Solutions Using Thermally Treated Egg Shell (Locally Available and Low Cost Biosorbent)

Abstract

The effluent water of any industries such as textile, leather, paper, printing, cosmetic, etc. contains large amount of hazardous dyes. There is a huge number of treatment process as well as adsorbent which are available in low cost adsorbents for the removal of hazardous dyes from aqueous waste by adsorption treatment. In this study, thermally treated egg shell was used as an adsorbent for the removal of methyl orange from an aqueous solution. All operating parameters like; adsorbent dose, contact time, particle size and initial concentration of methyl orange were effective on their removal efficiency of the dye.

Key words: Adsorption, egg shell, methyl orange and Uv-vis spectroscopy
