    (Springer, 2012) Mohd Talib Latif; Lim Wanfi; Norfazrin Mohd Hanif; Razarul Naim Roslan; Masni Mohd Ali; Idris Mushrifah
    This study aims to determine the composition of surfactants in the lake surface microlayer, rainwater, and atmospheric aerosols in the area surrounding Lake Chini, Pahang. Surfactants in the lake surface microlayer were taken from seven different stations around the lake, while samples of rainwater were taken from five different sampling stations. The samples of atmospheric aerosols were collected from the Lake Chini Research Centre which is in close proximity to the lake.

    Surfactants in the sea-surface microlayer and their contribution to atmospheric aerosols around coastal areas of the Malaysian peninsula
    (Elsevier, 2010) Razarul Naim Roslan; Norfazrin Mohd Hanif; Mohamed Rozali Othman; Wan Nurul Farah Wan Azmi; Xan Xue Yan; Masni Mohd Ali; Che Abd Rahim Mohamed; Mohd Talib Latif
    A study was done to determine the concentrations of surfactants on the sea-surface microlayer and in atmospheric aerosols in several coastal areas around the Malaysian peninsula. The concentrations of surfactants from the sea-surface microlayer (collected using rotation drum) and from aerosols (collected using HVS) were analyzed as methylene blue active substances and disulphine blue active substances through the colorimetric method using a UV-vis spectrophotometer.
