Quantitative Raman study of aqueous monoethanolamine (MEA) solutions of concentration ranging from 0 to 99 mass in the spectral region between 300 and 3100 cm� 1 was performed. Band envelopes were resolved with Gaussian Lorentzian function. Progressive growth of area under these peaks with increasing concentration was used as the parameter to construct calibration curve. Area ratio of selected peaks was plotted against MEA concentration to depict the relationship between MEA concentration and each area ratio. Correlation for A1460/A933 has coefficient of determination closest to unity and lowest mean squared area. MEA concentration can be calculated from the equation derived from correlation between A1460/A933 and MEA mass . © 2014 Trans Tech Publications, Switzerland. date: 2014 publisher: Trans Tech Publications Ltd official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84914146122&doi=10.4028%2fwww.scientific.net%2fAMM.625.709&partnerID=40&md5=e4369ff5571128e0091d4a41d7fb862c id_number: 10.4028/www.scientific.net/AMM.625.709 full_text_status: none publication: Applied Mechanics and Materials volume: 625 pagerange: 709-713 refereed: TRUE isbn: 9783038351818 issn: 16609336 citation: Wong, M.K. and Bustam, M.A. and Shariff, A.M.
