In determining the constituent elements of various alloys by ICP-OES, complete dissolution of the samples is indispensable. It is effective to use a dissolvent containing complexing agents to dissolve samples in which the constituent elements are easily hydrolyzed, because the hydrolysis of antimony and tin could be prevented by using a HNO_3-HCl mixture containing tartaric acid in these elements. By a dissolution method using a HNO_3-HCl mixture containing tartaric acid, the constituent elements in antimony and tin alloys could be exactly determined without the hydrolysis of analytical elements. Furthermore, when a mixed dissoivent of 35 ml of HNO_3 (diluted 1 + 1), 5 ml of HCl (diluted 1 + 1) and 1 g of tartaric acid was used, metallic germanium could be completely dissolved without volatilization as the chloride.
