Removal of methylene blue dye by burned coal from brick field and eggshell as an adsorbent
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 6, Issue 2
Abstract
Methylene blue (MB) is released with the effluent from textile, leather, paper and other industries. Study was conducted to observe the removal efficiency of MB dye from aqueous solution by burned coal and eggshell as adsorbents. The concentration of MB decreased from 25 ppm to 2.102 ppm for burned coal as an adsorbent and from 25 ppm to 0.656 ppm for eggshell powder as an adsorbent. Adsorption capacity of eggshell was higher than burned coal at pH value of 7. Approximately 3 million tons of burned coal is produced every year in Bangladesh and the price of burned coal is only about BDT 3.00 per Kg. Large amount of eggshell is also produced every day and it is available in our country. So the burned coal and eggshell particularly eggshell could be an excellent low cost bio-adsorbent for cationic dye removal.
