Present study deals with the lead removal from simulated wastewater using cost effective bio-adsorbent of mango seeds cover with kernel (M), and jamun seeds cover with kernel (JP). Lead removal optimization of adsorption parameters has been analyzed by using Response surface methodology (RSM). The optimum adsorption was attained at speed of 500 rpm, 60 mg, pH 6.5 and contact time of 120 min. The adsorption capacities are around 39.15 mg/g of M and 20.28 mg/g of JP bio-adsorbent, and also the maximum Pb removal were observed ̴ 94.85% and 92.78%, respectively. The regression coefficient was best fitted for both bio-adsorbents are Freundlich model and pseudo-first order reaction kinetic.
