Spectrophotometric determination of tartrate in the presence of citrate.
Methods are described for the determination of 5-30 mug of tartrate alone and of 15-60 mug in the presence of up to 6 mg of citrate, based on oxidation by 3 moles or 1 mole of periodate respectively. The iodate formed is determined spectrophotometrically at 350 nm as tri-iodide after reaction with iodide, the excess of periodate being masked with molybdate.
