Adsorption properties of As, Pb AND Cd in soft soil and meta sedimentary residual soil.

Arsenic, Lead and Cadmium were commonly found at industrial sites and turn out to be toxic at high concentrations. Two types of soil commonly found in Malaysia, namely meta sedimentary residual soil (RS) and soft soil (SS) were studied as an adsorbent for the removal of As, Pb and Cd. The physico-ch...

Arsenic, Lead and Cadmium were commonly found at industrial sites and turn out to be toxic at high concentrations. Two types of soil commonly found in Malaysia, namely meta sedimentary residual soil (RS) and soft soil (SS) were studied as an adsorbent for the removal of As, Pb and Cd. The physico-chemical properties and batch adsorption tests were conducted in order to evaluate the capability of these soils. The physico-chemical properties tested in this study include particle size distribution, Atterberg limit, pH of soils, surface area and pore size determination, soil mineralogy, soil composition and cation exchange capacity. Batch adsorption tests were performed by shaking 6g of soil in 30ml of solution. The concentration were fixed at 10mg/L while the contact time varies at 0.5, 1, 2, 4, 8, 12, 16, 20, 24, 48, 72, 96, 120, and 168 hours. The filtrates were then tested using Atomic Absorption Spectrometer (AAS) and the adsorption data have been correlated with both Freundlich and Langmuir isotherms. The results showed that the RS successfully adsorbed Pb and Cd while soft soil was effective in the removal of As. Both soils fitted well to Freundlich adsorption isotherm in the adsorption of As and Cd while Langmuir was best fitted in the removal of Pb. 2008 Conference or Workshop Item PeerReviewed application/pdf http://eprints.uthm.edu.my/2288/1/Adsorption_properties_of_As.pdf Abd Karim, Ahmad Tarmizi and Abdul Latiff, Ab Aziz (2008) Adsorption properties of As, Pb AND Cd in soft soil and meta sedimentary residual soil.
