The analysis of standard curve was produced and was found out that its R–Squared to be equal to 0.998. The effect of cement as an adsorbent to the removal of lead was conducted and was found out to have a percent removal of 1.724% to 4.598 %. Parametric study was done using a batch process and was conducted with the use of the following parameters: BFA:cement ratio, adsorbent pellets loading, and analyte concentration. Giving an amount of 90.15 % lead removed, the best combination of parameters having the highest amount of lead removal was found to be the following: 50:50 for BFA:cement ratio, 1 gram for pellets loading, and 70 ppm for analyte concentration. The effect of parameters introduced for the adsorption of lead was analyzed and found that the parameter, BFA:cement ratio, gave a significant effect. It was also found out that interaction (adsorbent pellets loading and analyte concentration) and interaction (BFA:cement ratio, adsorbent pellets loading, and analyte concentration) were significant. The regression equation for the parametric study was formulated and found out that the average percent lead removal be equal to 54.66 %. In the kinetics studies, the adsorption setup was used and the kinetic model equation used were pseudo–1st order and pseudo–2nd order models. It was found that pseudo–2nd order model was more appropriate for the study.
