Kandungan dan sumber alkohol lemak di dalam sedimen muara di Sungai Kapar, Selangor

A total of 13 fatty alcohols (C12- C24) including six branched compounds have been identified in seven surface sediment samples taken from Sungai Kapar, Selangor using computerized gas chromatography-mass spectrometry (GC-MS). Generally 65% of total fatty alcohols determined were short chain compoun...
