REMOVAL OF SYNTHETIC DYE ACID RED 186 FROM WATER BY ACTIVATED CARBON

Abstract

The adsorption of acid red 186(AR) onto activated carbon prepared from Libyan farms was studied, the effect of solution pH, contact time, adsorption dose and initial dye concentration was evaluated. The adsorption studied included Langmuir and Freundlish isotherms were applied to experimental results. The experimental results fitted very well to both adsorption isotherms. The mixture mono layer capacity obtained from Langmuir is q_e =7.62mg/g for activated carbon (100-45um) and q_e=7.194mg/g for activated carbon (lees than 45um).Therefore, activated carbon has the potential to be used as a low cost eco-friendly adsorbent for removal “activated carbon” dye from aqueous solution.
