Abstract

Column experiment is a very useful apparatus that can be used to study the migration and attenuation of heavy metals (HMs) through a compacted soil column. In this recent study, column experiment was conducted on some natural soils from Selangor area in Malaysia using different types of heavy metals, namely Pb, Cu, Ni and Zn. Prior to testing, all soils were thoroughly characterized for their physical, chemical and mineralogical properties. Three soil samples, namely Sungai Besar marine clay (SBMC), and weathered metasediments from Batang Berjuntai (HMS) and river alluvium soil from Ampar Tenang (ARA) were used in this study. All soil columns were permeated using laboratory made solution with concentrations of heavy metals ranging from 516-567 mg/L, pH was 1.5 and conductivity 5.93 mS/cm. The experimental test results were analysed in terms of their breakthrough curves, and the retention-migration profiles from top to bottom of the soil column. The breakthrough curves show that the SBMC sample has better adsorption capacity on heavy metals compared to other soils; resulting less migration of heavy metals through the soil column. Less retention means high concentration of heavy metals is detected in the pore fluid. the test result also reflect the influence of soil origin in adsorption of heavy metals, where soil characteristics and surface properties contribute very significantly to the adsorption of heavy metals by soils.
