Determination of brominated phenols in water samples by on-line coupled isotachophoresis with capillary zone electrophoresis
Original language description
A method for determination of nine brominated phenols as environmental risk compounds was developed by on-line coupled capillary isotachophoresis and capillary zone electrophoresis (ITP-CZE). For ITP step, 1 x 10(-2) mol L-1 hydrochloric acid with 3 x 10(-2) mol L-1 ammediol pH 9.1 was used as the leading electrolyte, and 3 x 10(-2) mol L-1 beta-alanine with 2 x 10(-2) mol L-1 sodium hydroxide pH 10.05 was used as the terminating electrolyte. As the background electrolyte for CZE separation, 2.5 x 10(-2) mol L-1 beta-alanine with 2.5 x 10(-2) mol L-1 lysine pH 9.6 was used. All electrolytes contained 0.05% or 0.1% (m/v) hydroxyethylcellulose to suppress the electroosmotic flow. UV detection at wavelength 220nm was used. Detection limits in order of tens of nmol L-1 were achieved. Good repeatability of migration times (less than 0.33% RSD) and good repeatability of peak areas (less than 7.19% RSD) at concentration level 5 x 10(-8) mol L-1 were observed.
