- A method was developed, in which HANs in potable water are determined by solid phase microextraction (SPME). The analytical procedure is relatively quick and simple, yielding satisfactory recoveries, which range between 80% and 90%. The detection limit was evaluated as 0.04 to 0.08 mg/m[3]. The method is very sensitive with a relative standard deviation lower than 10%. A major advantage is its remarkable sensitivity, which makes it possible to limit the matrix effect. The analytical method proposed was made use of to determine HANs concentrations in the treated water from the Northern and Central Waterworks of Warsaw. HANs content was found to be insignificant (totalling up to 5 mg/m[3]). Determined were predominantly dichloroacetonitrile, bromochloroacetonitrile and dibromoacetonitrile. Brominated HANs detected in the water intake for the Northern Waterworks occurred at slightly lower concentrations.
