Question

Peocedures involved when using Surface enhanced Raman spectroscopy(SERS) to determine the quantitative nature of Sudan-iv dye in adulterated palm oil.

Expert Solution

Step 1

Sudan –IV is a fat-soluble azo dye which is used in coloring tiles, polishes. And it is banned by the International Agency for Research on Cancer (IARC) because of its carcinogenic and mutagenic properties.

SERS is a very sensitive and vibrational spectroscopic technique based on Raman Scattering employed to detect the concentration of Sudan (IV).
