Abstract
Leachates of Cr and Ni from stainless steel utensils viz., frying pans , bowls and tumblers, have been investigated, by exposing the utensils to decinormal solutions of citric, tartaric and lactic acids and to s ome common Indian drinks. A comparison of observed results indicate th at the complexation of metal ions with organic acid anions is most vit al and metal leaching is largely a function of the availability of fre e anions. The intake of Cr and Ni by human beings has also been calcul ated. (C) 1997 Elsevier Science B.V.
