Determination and Characterization of Photocatalytic Products of Linear Alkyl Sulphonate by High Performance Liquid Chromatography and Nuclear Magnetic Resonance

In this study, Linear Alkyl Sulfonate (LAS) as anionic detergent active compounds was treated with photocatalytic method. The method degrades LAS to form CO2 and H2O. Time variations performed to the photocatalysis was conducted hour to hour, from 1 to 5 hours. Determination of LAS concentration was carried out using methylene blue active substances (MBAs), whereas characterization of LAS structure was observed using high performance liquid chromatography (HPLC) and nuclear magnetic resonance spectrometry (NMR). The results showed that 69.9% of LAS decomposes 65.1% of CO2 are formed.
