Activated carbon prepared from sawdust is endeavored as adsorbent for the removal of reactive dye, namely Remazol Red (RR) from aqueous media. The adsorption of RR has been studied onto activated sawdust at various particle size, adsorbent dose, temperature and pH values. The adsorptions of the above mentioned dye were designed for the Langmuir and Freundlich Isotherms. Pseudo first and second order kinetic models were used to calculate the amount adsorbed at equilibrium (q e ). The calculated values of q e for pseudo-second order equation were found to be in good agreement with those of experimental values. The monolayer capacity (q m ) for treated sawdust (8.00 mg g -1 ) is greater than commercial charcoal (0.074 mg g -1 ). It is established that treated sawdust has been used as a better adsorbent for the removal of RR as compared to commercial charcoal. This process may eventually be used to get industrial waste free purified water.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
