The treatment of wastewater generated during industrial, domestic and agricultural activities is a matter of concern worldwide. The presence of heavy metals as a major pollutant in water calls for serious attention due to its persistent, non- biodegradability, accumulative and toxic nature. This research explored the potentials in mango seed in the raw, activated carbon /zinc oxide Nano composite forms(M(raw), M(NC) for the removal of Lead from aqueous solutions. The adsorption capacities of the adsorbents were determined by the application of atomic adsorption spectrophotometric methods in a batch adsorption study under varying conditions of temperature, time, dosage, concentration and pH, and the results showed high adsorption capacities with very high percentage removal. The adsorption was favored with maximum adsorption at temperature of 45 0 c, equilibrium sorption time of 180mins.In general adsorption capacities increased with increase in varying conditions except for dosage. The experimental data were sampled on different kinetic models (pseudo-first order, pseudo-second order, intra-particle diffusion a (Langmuir and Freundlich). The results indicates pseudo second order kinetic and intra particle diffusion models fitted the sorption process better than pseudo first order and liquid film diffusion models respectively. These results implied chemisorption process and pore penetration of the adsorbates. The thermodynamic studies revealed a chemisorption and spontaneous process with increased degree of disorderliness. The results obtained in this study revealed that Mango seed especially in the activated/zinc Nano composite form is an efficient and effective adsorbent in the removal of Lead from aqueous solution.
