The effects of temperature, the salt KCI and pH on the said adsorption process have been also examined. The results have been analyzed in terms of Langmuir equation wherever applicable. An assessment of the comparative adsorption of EB and MB under the studied conditions in terms of the energetics of the process has been attempted.
