摘要：

A study has been made of the polarographic (DC and DPP) behaviour of the food dyes Sunset Yellow and Tartrazine in acid and alkaline media and in the absence and presence of polyvinylpyrrolidone. Methods are proposed for the determination of both dyes by DPP over a concentration range of 0.1-10 ppm. The methods have been applied to their determination in soft drinks. © 1990.
