Abstract

The degradation of LAS was investigated in distilled, tap and sea water. The analysis of LAS in HPLC showed that the number and size of peaks decreased during the test. Degradation began the first day and continued rapidly. LAS degraded in 20 days 84.8% in distilled water, in 14 days 84.8% in tap water and in 14 days 93.2% in sea water. The number of peaks were diminished and their areas reduced on HPLC chromatograms of LAS during the tests. The degradation of LAS was ranked as sea water > tap water > distilled water.

Keywords: LAS, degradation, distilled, tap, sea water.
