Rapid analysis method of an organic compound of stainless steel sulfuric acid pickling solution

摘要

PROBLEM TO BE SOLVED: To provide a quick analytical method for an organic compound in a stainless steel sulfuric acid pickle, in which the organic compound such as an acid pickling promoter or the like in the stainless steel sulfuric acid pickle can be analyzed simply and quickly without the special pretreatment of the organic compound. SOLUTION: In this quick analytical method for an organic compound in a stainless steel sulfuric acid pickle, the stainless steel sulfuric acid pickle is changed preferably into a mobile phase so as to be introduced to the separating column of a high-performance liquid chromatograph, an eluate from the separating column is guided to a detector, and the organic compound in the stainless steel sulfuric acid pickle is quantitatively determined. The separating column is a graphite carbon column, and a liquid which contains a hydrophilic organic solvent is used as the mobile phase of the high-performance liquid charmomatograph.
