title: Determination of vanadium: an optimization of the gallic acid persulphate method.
abstract: An optimization procedure for the gallic acid-persulphate method for the ultratrace determination of vanadium is reported. The optimization step has improved the sensitivity by a factor of three. The linearity range of the calibration graph is also extended.
