Composition and source apportionment of surfactants in atmospheric aerosols of urban and semi-urban areas in Malaysia. Chemosphere, 91(11), 1508-1516.https://repoemc.ukm.my/handle/123456789/519This study was conducted to determine the composition and source apportionment of surfactant in atmospheric aerosols around urban and semi-urban areas in Malaysia based on ionic compositions. Colorimetric analysis was undertaken to determine the concentrations of anionic surfactants as Methylene Blue Active Substances (MBAS) and cationic surfactants as Disulphine Blue Active Substances (DBAS) using a UV spectrophotometer.enSurfactantSource apportionmentAtmospheric aerosolUrban areaSemi-urban areaJournal
