Fa. Chmilenko et Lv. Baklanova, ATOMIC-ABSORPTION DETERMINATION OF STANDARDIZED METAL IMPURITIES IN WINES USING ULTRASOUND, Journal of analytical chemistry, 52(11), 1997, pp. 1093-1098
A complex of rapid procedures for the determination of Fe, Zn, Cu, Ph,
Cd, and Hg in wines was developed. The use of ultrasound for degassin
g solutions, removing ethanol, and intensifying the decomposition of o
rganic compounds enhances the rapidity and the precision of analysis.
