Abstract

The aim of this study is to investigate low cost, easily available, and sustainable solutions to remove heavy metal ions from the effluent from geotextile tubes and wastewater. Three soils and three cellulosic materials have been used to study their effectiveness in adsorbing as well as retaining heavy metal ions when mixed in contaminated aqueous solutions. The effect of different particle sizes, physical and chemical properties of soils in adsorption has been studied by performing a batch adsorption test in15% concentration (sediment: heavy metal solution) slurry. Similarly, batch adsorption tests were also conducted on cellulosic materials (Peanut hulls, Jute fibers, Kraft pulp) mixed with heavy metal solution. The studied heavy metal ions are lead (Pb), copper (Cu), cadmium (Cd), and zinc (Zn). The samples collected from batch adsorption tests were tested for heavy metal ions using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES).
