摘要：

Two methods are described for the gravimetric determination of the hexafluoroantimonate anion with tetraphenylarsonium chloride and nitron as precipitants. In addition, a spectrophotometric method for this anion with ferroin as reagent is described. Hydrolysis of the anion is avoided by using stock solutions of KSbF6 in N,N-dimethylformanude and adding these directly to concentrated aqueous solutions of the analytical reagent. Interference studies are included on a number of anions. © 1968.
