Abstract
Sodium erythrosin and polyvinylpyrrolidone (PVP) will form a complex in aqueous solution. The effects of pH and PVP concentration have been investigated and a spectrophotometric method developed for the quantitation of the dye in oxymix, a PVP containing pharmaceutical system. It has also been determined that PVP improves the color stability of an erythrosin solution over a broad pH range.
