| dc.description.abstract | The application of Maredan natural clay as an adsorbent has several advantages, such as lower cost, abundant availability and good adsorption efficiency. In this research, Maredan natural clay was used to adsorb lead in water. The purpose of this research was determine the optimum contact time and optimum concentration of adsorbate, the adsorption isotherm and adsorption kinetics model of the adsorbent in lead adsorption process using Maredan natural clay. The adsorption used batch method with contact time variations of 10, 20, 30, 40 and 50 minutes and variations in adsorbate concentration of 40, 60, 80 and 100 ppm. The concentration of adsorbate adsorbed was determined using AAS. Characterization of the adsorbent before and after adsorption process was carried out using a FTIR instrument to determine the bond vibrations and functional groups of Maredan natural clay. The optimum contact time and adsorbate concentration of this research was obtained at 20 minutes and adsorbate concentration of 40 ppm, with adsorption efficiency of 77,02%. The adsorption isotherm for lead adsorption using Maredan natural clay was found to follow the Langmuir isotherm with R2 coefficient of 0,9314. The kinetic model of this research followed a second pseudo order kinetic model with and R2 coefficient of 0,9992. | |
