The results showed that though the introduction of SDS could inhibit the TCE degradation, the inhibiting effect was less with the increasing SDS dose. In the presence of SDS, TCE could be completely removed with the SPC\/Fe(II)\/TCE molar ratio of 40\/80\/1. Experiments with free radical probe compounds and radical scavengers elucidated that TCE was mainly oxidized by both HO\u00b7 and \n\n<jats:inline-graphic xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"graphic\/wer1309-math-0001.png\" xlink:title=\"urn:x-wiley:10614303:media:wer1309:wer1309-math-0001\"\/>.
