- W2240869530 abstract "A commonly used method for the separation of barium from strontium is that of the precipitation of barium as chromate under careful control of pH, but it is difficult to apply when a large amount of strontium is present. A modification of this procedure by the use of hydroxyethyliminodi-acetic acid or nitrilotriacetic acid as a masking reagent is offered. When potassium chromate is added to an ammoniacal solution containing barium, strontium, and a large excess of the masking reagent, only barium chromate is precipitated. The solution is heated for 10 min on a boilingwater bath, and then ice-cooled for 1 hr. After centrifuging, the washed precipitate is dissolved with phosphoric acid and the chromate is titrated with ferrous solution, using sodium diphenylaminesulfonate as an indicator. By this method, less than 0.1 m mole of barium can easily be separated from less than 0.8 m mole of strontium with little coprecipithtion. Nitrilotriacetic acid has stronger masking power than hydroxyethyliminodiacetic acid but it suffers from slight pH effect. Alkaline metal ions and common anions do not interfere but most of the anions which precipitate strontium, such as fluoride, nitrite, carbonate, oxalate, phosphate, etc., interfere. (auth)" @default.
