A method has been developed for the determination, by atomic absorption spectrophotometry, of calcium, magnesium, sodium, potassium, manganese and zinc in fruit juices. The metals may be determined by direct aspiration of the sample, suitably diluted with water, after removal of suspended matter by centrifugation. It is not necessary to ash the samples prior to analysis. Results are given for the analysis of different fruit juices, and figures are presented for the accuracy and reproducibility of the recommended procedures.
