Abstract�� A 8-hydroxyquinoline-5-sulphonic acid fluorescence spectrophotometry in sulphuric-phosphonic acid medium is proposed to determine trace of chromium in waste wash acid of strip steel with triotylamine-methenyl chloride as separation-enrichment system.This method is simple ,sensitive and highly accurate.
