| dc.description.abstract | Natural clay is a part of earth that has pores and active sites on its surface. In this case the clay can be used for removing heavy metal pollutants because it has properties as an adsorbent. The purpose of this study is to determine adsorption rate constant (k) of natural clays activated NaOH through the metal adsorption of Pb(II) under the influence variation of concentration, temperature and contact time. This study uses natural clay from Talanai Village activated with a concentration of 1 M NaOH (L1) and clay without activation (Lo) as a metal adsorber Pb(II) in the solution of Pb(NO3)2. Activation of clay with NaOH was done by immersion method, followed by calcination process of at a temperature 600oC. The results showed that the maximum absorption of Lo is at concentration of 10 mg/L and L1 at 20 mg/L. Lo is the maximum at temperature 30oC and L1 at 50oC. Adsorption kinetics in this study meets pseudo orde-two correlation with coefficient R2 value (0.996 to 0.999). The rate constant (k) adsorption of Lo is -0,864 mgg-1 min-1 and L1 is 5.336 mgg-1 min-1 | en_US |
