Abstract A quantitative method is presented for the determination of cadmium at low levels (5–20 ppm) in water-soluble color additives by atomic absorption spectroscopy. Absorption measurements were made on aqueous solutions of typical color additives to which known amounts of cadmium had been added. The method requires no pretreatment of sample and should be applicable to all water-soluble color additives.
