PROBLEM TO BE SOLVED: To provide an organic acid decomposition method capable of reducing treatment cost (including equipment costs), and an organic acid decomposition apparatus. SOLUTION: The organic acid decomposition method has an oxalic acid decomposing process for decomposing oxalic acid in a decontamination waste liquid containing formic acid and oxalic acid in the presence of hydrogen peroxide and divalent iron ions and a formic acid decomposing process for decomposing formic acid in the decontamination waste liquid, wherein oxalic acid is decomposed, under a contact condition with a stainless steel catalyst by hydrogen peroxide.
