摘要 Enzymeless flow injection analysis of 2,4,6-trichlorophenol (2,4,6-TCP) based on preoxidation by ammonium cerium (IV) nitrate will be presented in this work. A preoxidation scheme is applied for 2,4,6-TCP determination without any enzyme treatment. This preoxidation scheme can provide a determination method with low cost and non-conductive polymerization reaction of 2,4,6-TCP. In proposed scheme, the 2,4,6-TCP is oxidized to 2,6-dichloro-1,4-benzoquinone by ammonium cerium (IV) nitrate and the 2,6-dichloro-1,4-benzoquinone can be detected at low reduction potential. The linear range of 2,4,6-TCP determination was 0.4 to 750 M with correlation coefficient (R2) 0.9999 and the estimated detection limit (S/N=3) was 40 nM which were demonstrated by flow injection analysis. Twenty successive detect of 100 M 2,4,6-TCP showed the relative standard deviation was 1.56%. Several 2,4,6-TCP structure-like compounds were studied as interferences including 2,4-dichlorophenol, 2-chlorophenol, phenol and 4-aminophenol. No obviously influences were observed. Two water samples which were collected from local farm and pool were adopted as analytical application. The recoveries of two water samples are 105.2% and 107.5%, respectively. An easy operation and enzymeless treatment detection scheme of 2,4,6-TCP is illustrated in this work
