Equilibrium isotherm studies of methylene blue from aqueous solution unto activated carbon prepared form strychnos potatorum seed. International Journal of Applied Biology and Pharmaceutical Technology. 2012 Jul-Sept; 3(3): 27-31.0976-4550http://imsear.searo.who.int/handle/123456789/163766Methylene blue adsorption from aqueous solution onto activated carbon prepared from strychnos potatorum seed was investigated under various experimental conditions. Batch mode experiments and equilibrium isotherm studies were conducted to assess the potential of the above activated carbon for the removal of Methylene blue from aqueous solution by varying the following three parameters: initial concentration of Methylene blue dye solution, adsorbent dose on the uptake of dye from the solution, and pH. The equilibrium data obtained were fitted to Langmuir and Freundlich isotherm models.enSorptionIsothermsActivated carboncarbonizationMethylene blueLangmuir modelFreundlich modelArticle
