Abstract

The objective of this study is to investigate the effect of pH on the adsorption, to determine isotherm and kinetic of adsorption of Pb (II) ions by dried cattail leaves. Cattail leaves was harvested from Kampung E Lake, Universiti Malaysia Sabah. Cattail leaves was clean and dried. Experiment was carried out by agitating dried cattail leaves with Pb (II) solution at different pH. Sample was filtered and analyzed after reach designated contact time. The adsorption of Pb (II) ions is increase as the pH is increase. This study followed Langmuir isotherm with maximum adsorption capacity 57.14 mg/g. The adsorption kinetic followed the pseudo-second order. This indicates that the chemisorption involved in adsorption of Pb (II) ions.
