Adsorption of sulfide S2- from aqueous solution on commercial charcoal was studied using conductometric technique. A proportionally constant for concentration of S2- and its conductance was obtained by measuring conductance of S2- solution over a concentration range of 0.000526614850.02 M. The time-dependent measured conductance of S2- solution was converted to concentration using the obtained constant. The adsorption data were analyzed by both Freundlich and Langmuir isotherms. A surface coverage equal to 2.5 mg per gram of charcoal was obtained. The adsorption was found to follow first-order kinetics having rate constant equal to 2.65 2661620 1026614853 s-1.
