- •
Selective DSPME was developed for the speciation of Se prior to ICP-OES detection.
- •
Speciation of inorganic Se species depended on the pH of the sample.
- •
Low LOD and LOQ with relatively high preconcentration factor were obtained.
- •
The DSPME procedure was validated and applied in real water samples.
