Abstract

Six soil samples represent the major soil series used for agricultural production such as Rubber, oil palm, cocoa and rice in Malaysia were sampled to study the adsorption capacity of zinc which consider as an environmental harmful metal. The objectives of this study were to report experimental results on adsorption of Zn and to determine the adsorption mechanism of these soils using different models. After soil characterization, sorption isotherms were prepared using the six different soils and initial zn concentrations ranged from 5 to 100 mg L-1. The soils show different retention capacity. The highest sorption capacity was found in Melangit soil. Because of the presence of calcite and high pH, the precipitation of zinc was the dominate factor. Where the high Zn adsorption in Kundor soil attributed to the characterization of the soil. The high CEC and the clay content were the main factors. Zn adsorption isotherms corresponding to all soils adjusted to Langmuir and Freundlich empirical models. Results showed that Freundlich equation has highest value of correlation coefficient (r2) comparison to Langmuir equations and that all soils have high affinity for Zn sorption. Therefore the main factors controlling the adsorption of Zn in these alluvial soil are precipitation and ionic adsorption.
