Abstract
The disolution of neutron-irradiated metallic nickel in an artificial sweat formulation has been studied. Variations in dissolution rate were found over a pH range of 3.5 to 6.5, a temperature range of 10 to 40.degree. C and for times up to 6 h. The presence of oxygen increases the dissolution rate markedly. Typical dissolution rates at 30.degree. C vary from 2 .cntdot. 10-7 g Ni .cntdot. cm-1 .cntdot. min-1 at a pH of 3.5, to 1 .cntdot. 10-9 g Ni .cntdot. cm-2 .cntdot. min-1 at a pH of 6. The relevance of the data to clinical aspects of nickel dermatitis is discussed.Keywords
