To study the pH effect on adsorption of Methylene blue solution by using coconut shell, Rice husk and coalmine charcoals

Industrial development takes place in this century very fast. During this development nobler of colors and dyes are used. These dyes are responsible for the various pollution like water, soil, and other pollution. Mostly the industrial water was discharged into rivers, pods and other water bodies. To overcome this problem, it become necessary to remove these dyes from the industrial discharge. One of the solution is that the industrial effluent must be treated before the discharge into other water bodies. We have developed different type of the activated natural charcoal from the coconut shell, cotton fiber, mango wood, camphor wood, neem wood, rice husk, wheat bran, coal mine and these charcoals used to the adsorption of Methylene Blue dye.Some type of charcoals shows the excellent adsorption for Methylene Blue dye. Around 90-95% of the dyes get adsorbed over it. These are low cost, easy to prepare and have good efficiency. The work focused on removal of Methylene Blue dye using coconut shell, rice husk, and coal mine activated charcoals and improve the capacity of these charcoals. We studies the pH effect on adsorption of Methylene Blue solution by using these charcoals. Finally the experimental data showing the given activated carbon from coconut shell, rice husk and coal mine are in specific pH extensively in removal of Methylene Blue dye from waste water.
