| dc.description.abstract | Clay is a natural inorganic polymer this has aluminosilicate hydrate form. It is widely known as the fraction of fine colloids (± 2 μm) of soil, sediment or rock. If the clay absorbs water, it is like a plastic form and instead will harden if dehydrated. Clay can be used as an absorber of heavy metals present in the aquatic environment and solid waste, such as Pb which is toxic for humans and animals. There are many method that have been developed to reduce the concentration of Pb ions in the environment, one of which is through adsorption method. This research has been done to study adsorption kinetics of metal ion Pb2+ on natural and modified clay. This natural clay is physically activated. This research was conducted with various concentration of Pb2+, adsorption temperature, and contact time respectively. Analysis is performed using the Atomic Absorption Spectrophometry method. The result showed that the optimum for the absorption at initial concentration 7.8658 mg/L (L0 and L1) and temperature 30oC. The adsorption mechanism of Pb(II) cation-Talanai clay follows the pseudo second-order kinetic with the maximum uptake time for L0 is 120 minutes and L1 is 300 minutes | en_US |
