Abstract
Official abstract text for this publication.
A precipitate and/or an inclusion in a metal material are extracted by electrolysis using an electrolyte solution. The electrolyte solution contains an adsorbent physically adsorbed and/or chemically adsorbed to any metal other than a matrix metal of the metal material. The extracted precipitate and/or inclusion can be quantitatively analyzed with high accuracy.
First claim
Opening claim text (preview).
1 - 11 . (canceled) 12 . A method of extracting a precipitate and/or an inclusion, comprising extracting the precipitate and/or the inclusion in a metal material by electrolysis using an electrolyte solution, wherein the electrolyte solution contains an adsorbent physically adsorbed and/or chemically adsorbed to any metal other than a matrix metal of the metal material. 13 . The method according to claim 12 , wherein the electrolyte solution contains a solvent, and a specific gravity of the adsorbent is larger than a specific gravity of the solvent. 14 . The method according to claim 12 , wherein the electrolyte solution contains an agent that forms a complex with the matrix metal. 15 . The method according to claim 12 , wherein the metal material is a steel material. 16 . The method according to claim 12 , wherein the any metal is Cu. 17 . A method of quantitative analysis of a precipitate and/or an inclusion, comprising quantitatively analyzing the precipitate and/or the inclusion extracted by the extracting method according to claim 12 . 18 . An electrolyte solution that extracts a precipitate and/or an inclusion in a metal material by electrolysis, the electrolyte solution comprising an adsorbent that is physically adsorbed and/or chemically adsorbed to any metal other than a matrix metal of the metal material. 19 . The electrolyte solution according to claim 18 , further comprising an agent that forms a complex with the matrix metal. 20 . The electrolyte solution according to claim 18 , comprising a solvent, wherein a specific gravity of the adsorbent is larger than a specific gravity of the solvent. 21 . The electrolyte solution according to claim 18 , wherein the metal material is a steel material. 22 . The electrolyte solution according to claim 18 , wherein the any metal is Cu. 23 . The method according to claim 13 , wherein the electrolyte solution contains an agent that forms a complex with the matrix metal. 24 . The method according to claim 13 , wherein the metal material is a steel material. 25 . The method according to claim 14 , wherein the metal material is a steel material. 26 . The method according to claim 23 , wherein the metal material is a steel material. 27 . The method according to claim 24 , wherein the any metal is Cu. 28 . The method according to claim 25 , wherein the any metal is Cu. 29 . The method according to claim 26 , wherein the any metal is Cu. 30 . The electrolyte solution according to claim 19 , further comprising a solvent, wherein a specific gravity of the adsorbent is larger than a specific gravity of the solvent.
