- •
The simultaneous determination of metal ions based on SPES and UV-Visible couple with multivariate calibration spectroscopy was proposed.
- •
The spectra of the analytes on the membranes were measured directly without eluting.
- •
The method was used to quantify trace cobalt (II) and zinc (II) in three real samples.
- •
The proposed method is simple, sensitive and selective.
- •
The applicability of the method can be extended to other analytes.
