摘要： An improved optical method for determining metal or a metal compound thereof in a sample with organic impurities. The optical method comprises of solvating the metal in a liquid medium and then mixing this liquid medium with an optical indicator and then measuring the presence of the metal. The improvement lies in removing any organic impurities by the addition of an additive, where the said additive is removed before the optical indicator is added.
