This paper reports the results of the study on the performance of low-cost adsorbent such as NCRH in removing lead. The adsorbent materials adopted were found to be an efficient media for the removal of lead in continuous mode using fixed bed column. The fixed bed column experiment was conducted in a column having a diameter of 2 cm with 10 mg/l Pb(II) solution at a bed depth of 10 cm maintaining a constant flow rate of 10 ml/min. The breakthrough and exhaust time were found to be 3.7 and 11.21 h, respectively. Height of adsorption zone was found to be 10.32 cm and the rate at which the adsorption zone was moving through the bed was 1.38 cm/h. The percentage of the total column saturated at breakthrough was found 47.6 %. The value of adsorption rate coefficient (K) and adsorption capacity coefficient (N) were obtained as 0.0524 l/(mg h) and 1712 mg/l, respectively.
