A Carbon adsorbent derived from Fly Ash was used for the Removal of Pb (II) from aqueous solution. Sorption of Metal ion has been studied as a function of contact time, temperature, PH of the Solution and metal ion concentration these factor have Remarkable positive effect on sorption process. the Adsorption data of Fly Ash at different Initial Concentration was fitted to frendlich & Langmuir adsorptions Isotherms and monolayer’s sorption capacity determined was 72 (PH 5.0 temperature 27⁰C). Thermodynamic parameter indicated that the sorption is Exothermic spontaneous with a greater affinity of metal species for the adsorbent.
