Unformatted text preview: of the wo rld, it is equally important to conduct research work like this in the Philippines where stranding occur on an average of 14 events per year based on a 12-year data computation, and where marine mammals are regarded as human food sources. Via the process of biomagnification, public health is greatly at risk. In addition, it is also important to measure chronic versus acute exposures of marine mammals. Long -term exposure to relatively low levels of some pollutants may be more damaging to a population’s continued success, than a single, high impact event. ENV-O12 REMOVAL OF MERCURY(II) ION FROM AQUEOUS SOLUTION BY USING RICE RESIDUES 1 S. T. Song, N. Saman, K. Johari and 1 1 1,2* H. B. Mat 1 Advanced Material and Process Engineering (AMPEN) Research Group, Fa culty of Chemical and Natural Resources Engineering, Universiti Teknologi Malaysia, 81310 UTM Skudai, Johor, Malaysia 2 Novel Materials and Process Technology (NoMPTech) Research Group, Institute Ibnu Sina for Fundamental Science Studies, Universiti Teknologi Malaysia, 81310 UTM Skudai, Johor, Malaysia E-mail: Lignocellulosic wastes such as rice husk and rice straw can be found abundantly which are also inexpensive and having the potential to be low-cost sorbents for metal ion removal. In this study, pure and modified rice husk (RH) and rice straw (RS) were used as sorbents for mercury removal from aqueous solution. The pure RH and RS were chemically modified through alkali treatment. The sorbents were characterized by Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), and Atomic Absorption Spectrophotometer (AAS). In this study, it was found that the rice husk showed a better adsorption capacity compared to rice straw and only alkali modified rice husk gi ves significant difference on Hg(II) adsorption capacity. 93 23rd-25th June 2010 3rd ICYC 2010 Universiti Sains Malaysia ENV-O13 PREPARATION OF POLY(HYDROXAMIC ACID)-POLY(AMIDOXIME) CHELATING RESIN FROM ACACIA CELLULOSE FOR HEAVY METALS REMOVAL Simon Siew Yong Wen, M...
