The disposal of industrial waste has become a significant environmental issue. In this work, industrial waste, heavy oil fly ash (HOFA) produced from burning heavy oil in the power station was investigated to produce activated carbon (AC) asadsorbent from modified HOFA for lead removal. Batch experiments of lead removal were conducted at a different adsorbent dose and time contact. Equilibrium isotherm results with a good match in with Freundlich model with R2 =0.971which shows the heterogeneous surface of adsorbent and multilayer of adsorbate on the surface of (AC). A maximum adsorption capacity of 10mg/g at equilibrium was achieved. Kinetic study showed rapid adsorption at first 60min, with good matching to second order pseudo model with R
