摘要
PROBLEM TO BE SOLVED: To provide a solution for chemical analysis of a zinc-iron alloy group 2-layer plated steel board, and the chemical analysis method using it wherein a sticking amount of each plated layer and composition are accurately measured by selectively melting lower plated layers in a short time. SOLUTION: In a solution for chemical analysis of a zinc-iron alloy group 2-layer plated steel board, a base material plated layer 12 of a zinc-iron alloy group 2-layer plated steel board 10 which comprises a base metal plated layer 12 with low iron content and a surface part plated layer 11, with high iron content, allocated on the base material plated layer 12 is selectively melted, so that the surface part plated layer 11 is separated from the zinc-iron alloy group 2-layer plated steel board 10. The chemical analysis solution comprises such neutral salt for eluting zinc in the base material plated layer 12, an oxidizer for oxidizing eluted iron ion, and a chelating agent for stabilizing an oxidized iron ion as chelate compound.
