Capillary zone electrophoresis determination of fluoride in seawater using transient isotachophoresis.

We developed capillary zone electrophoresis (CZE) with indirect UV detection for the determination of fluoride (F) in seawater using transient isotachophoresis (tITP) as an on-line concentration procedure. A method of correcting sample salinity effects was also proposed so that F concentrations were obtained using a calibration graph. The proposed method is simple: it requires no sample pretreatment aside from dilution.
