Spillage of water polluting substances via industrial disaster may cause pollution to our environment. Thus, reversed-flow gas chromatography (RF-GC) technique, which applies flow perturbation gas chromatography, was used to investigate the evaporation and estimate the diffusion coefficients of liquid pollutants. Selected alcohols (99.9% purity) and its mixtures were used as samples. The evaporating liquids (stationary phase) were carried out by carrier gas-nitrogen, 99.9% purity (mobile phase)

The findings of this work showed the physicochemical measurements may vary depending on the composition of water and alcohol mixtures, temperature of the mixtures, as well as the types of alcohol used. This study implies that there is a variation in the results based on the concentration, types and temperature of the liquids that may contribute in the references for future research in the area of environmental pollution analysis. ABSTRAK Limpahan bahan-bahan pencemaran melalui bencana industri boleh menyebabkan pencemaran kepada alam sekitar kita. Oleh itu, teknik gas kromatografi aliran berbalik (KTAB) yang mengaplikasikan teknik kromatografi gas aliran terganggu digunakan bagi menentu ukur kadar penyejatan dan menganggar pekali resapan bahan-bahan pencemar. Alkohol terpilih (99.9% darjah kepekatan) dan campuran telah digunakan sebagai sampel. Cecair menyejat (fasa penyebaran) telah diangkut oleh gas pengangkut iaitu nitrogen, 99.9% ketulenan (fasa persampelan) ke pengesan. Keputusan kajian ini menunjukkan ukuran fiziko-kimia mungkin berbeza bergantung kepada komposisi air dan alkohol di dalam campuran, suhu campuran dan jenis alkohol yang digunakan. Kajian ini menunjukkan bahawa terdapat perubahan keputusan berasaskan kepada kepekatan, jenis alkohol serta suhu campuran kajian, dan ia boleh menyumbang kepada rujukan untuk kajian akan datang dalam bidang analisis pencemaran alam sekitar.
