Modified Stannous Chloride Reagent for Orthophosphate Determination
An inherent weakness in the stannous chloride method now being used for the determination of orthophosphate is the instability of the stannous chloride reagent. In order to prolong the shelf life of this solution, a number of preservative techniques have been suggested. These include: storage of the reagent in a cool place, in a refrigerator, or in an aspirator bottle; floating the reagent on a layer of mineral oil; and, the addition of mossy tin. The reagent may be modified to give excellent shelf life without the need for preservative techniques.
