Development of colorimetric chemodosimeter arrays for determination of anions
Original language description
Halide (Cl-, Br-, I-) and hydrogencarbonate salt are important for maintaining homeostasis, environmental monitoring and are also present in foods and beverages such as in natural mineral waters. The azodyes such as 4-(2-pyridylazo)resorcinol (PAR) or 1-(2-pyridylazo)-2-naphtol (PAN) are widely utilized chromogenic reagents for determination of a number of metal ions. Unfortunately, the determination of metals is in some cases hampered by the presence of interfering anions, which impact the change in color of the dye-metal complex. However, we found that the change in color of some metal-azodye complexes may be utilized for determination of some anionic analytes. Since the color change in aqueous solution caused by a ligand substitution reaction is sufficiently large (cca. 50 nm), the studied systems were used to establish colorimetric chemodosimeter array devices for analysis of salt mixtures and mineral water samples.
