Application Of Gc-Fid And Gc-Ms In The Analysis Of Residue Level Of Phthalate Esters Along The Klang River, Maheschandar Biaspal Jan 2001

Application Of Gc-Fid And Gc-Ms In The Analysis Of Residue Level Of Phthalate Esters Along The Klang River, Maheschandar Biaspal

Student Works (2000-2009)

"Phthalate Esters" ("PEs") are considered as major industrial wastes that can cause pollution in the river water. A study of determination of the PEs in the Klang River water by the application of "Gas Chromatography'' ("GC'') with "Flame-Ionisation Detector" ("FID") will be carried out in this project. "Mass-Selective Detector" ("GC-MSD") will be used in the identification of phthalates compoW1d. A BP-5 non-polar capillary column will be used for the river water analysis. The river water will first be separated by a liquid-liquid extraction with an organic solvent. Toe extracts will then be subjected to a clean-up procedure to separate out …


Characterization Of Solvent-Extractable Hydrocarbons From Airborne Particulates And Street Dust Of Kuala Lumpur, Nasr Yousef M. J. Omar Jan 2001

Characterization Of Solvent-Extractable Hydrocarbons From Airborne Particulates And Street Dust Of Kuala Lumpur, Nasr Yousef M. J. Omar

Student Works (2000-2009)

The solvent-extractable hydrocarbons were identified in PM 10 airborne particles and roadside soil particles collected at eight locations in the city center and the suburb of Kuala Lumpur, Malaysia during the period from November 1998 to January 1999. Airborne particles were collected using high-volume PM1o sampler on glass fiber filters over 24 h average sampling period. After ultrasonic agitation with dichloromethane, the extracts were concentrated and fractionated on an alumina-silica column into three major fractions (aliphatics, aromatics and polar compounds). The aliphatics and aromatics fractions were then subjected to gas chromatography-mass spectrometric (GCMS) analysis. The major hydrocarbons identified in these …
