Abstract

A kinetic fluorimetric method has been proposed for determining trace oxalic acid based on the catalytic oxidation of rhodamine 6G with potassium dichromate in the solution of sulfuric acid. The linear range of the method is 0.8∼14.0 mg/L. The method has been used to determine trace oxalic acid in spinach and urine with satisfactory results.
