Abstract
The published data on chemical and analytical characteristics and the use of binary and ternary Pyrocatechol Violet complexes in spectrophotometric and novel optical methods of analysis are generalised. New promising trends are considered including studies of chromaticity characteristics of complexes of this reagent with various metal ions formed in the presence of cationic surfactants on the surface of anion-exchange resins or neutral sorbents aimed at increasing the sensitivity of determinations and developing new, more efficient test scales and optical sensors.
