Unformatted text preview: inst the residual metal concentrations in solution. The q versus C f sorption isotherm relationship was mathematically expressed by linear Langmuir and Freundlich models. The values of separation factor or equilibrium parameter between 0 and 1 indicate the favorable sorption for four tested metal on the biosorbent. Values of surface coverage approach nearly 1 with the increasing solution concentration which indicate the effectiveness of the biosorbent under invesigation.The non-living biomass of banana peel (Musa sapientum), present comparable biosorption 2+ 2+ 2+ 2+ capacity for Pb , Cu , Zn and Ni ions with other types (sources) of biosorbent materials found in previous literature. Efficiency of the biomass indicates that they are effective to remove metal ions from single metal solutions as well as in the presence of other co -ions with the main metal of solution. ENV-P4 PRELIMINARY ANALYSIS OF PHYSIO-CHEMICAL PARAMETERS AND DISTRIBUTION OF HEAVY METALS IN SOIL AND WATER OF EX-MINING AREA BESTARI JAYA, PENINSULAR MALAYSIA 1 Muhammad Aqeel Ashraf, Mohd. Jamil Maah and Ismail Yusuf 1 2 1 Department of Chemistry, Faculty of Science, University of Malaya, Kuala Lumpur 50603, Malaysia 2 Department of Geology, University of Malaya, Kuala Lumpur 50603, Malaysia E-mail: chemaqeel@gmail.com This paper includes preliminary soil and water analysis of former tin mining area Bestari Jaya. The whole catchment covers an area of 2656.31 hectors. The present study area covers 92 hectors of catchment which includes two water ponds that flow downstream to Sungai Ayer Hitam that ultimately ends up 2+ 2+ into Sungai Selangor. Initially physio-chemical parameters and concentration of heavy metals Pb , Zn , 2+ 2+ 3+ 2+ 2+ 2+ 2+ Ni , Co , As , Cu , Fe , Mn , Sn in soil and ponds were evaluated. The metals are extracted by nitric acid and hydrogen peroxide in a closed vessel microwave digestion system and analysed by using atomic absorption spectroscopy. The method is validated by using standard reference material (NIST SRM 4354, 1643e) and results w...
