The activating of corn stem by phosphoric acid and application in the removal of methylene blue

Abstract

This work is devoted to the development of the process for activating corn stalks by phosphoric acid and subsequently to carry out a comparative study of the blue adsorption capacity of methylene on raw corn stalks and elaborated activated carbon. The main objective is researching the optimal conditions for the production of activated carbon. The assessment of the quality of the activated carbon produced is carried out by monitoring the adsorption of an organic molecule, the methylene blue, in order to optimize the preparation conditions. This molecule presents the advantages of speed and simplicity thanks to the ease of colorimetric dosing. In addition, methylene blue is often used to assess the ability of an activated carbon to treat water and provide some information on the development of porosity during the activating.
