A colorimetric method has been developed to spectrophotometrically determine the poly(vinyl alcohol) (PVA) content of aqueous Cd(OH)/sub 2/ pastes. The method, which is based upon the formation of a blue PVA-iodine-boric acid complex, can quantitatively determine PVA in aqueous solution concentrations of 2-40 mg/L corresponding to PVA levels within the paste as low as 0.02%. Solution absorbance of the complex, however, depends upon the concentration of Cd/sup 2 +/ in solution necessitating cognizance of this level for routine quantitative analysis.
