Procedure

Ammonium sulfate solution was reacted with an equimolar amount of potassium chloride at about 20° C. and in the absence of free ammonia. The resulting washed potassium sulfate contained about 2.06% weight percent ammonium, while the resulting solution (mother liquor) contained about 4.85 weight percent dissolved sulfate. It was believed that the ammonium contained within the potassium sulfate most likely resulted from the co-precipitation of ammonium sulfate and potassium sulfate.
