Experimental techniques for quantitative precipitation, filtration, elution, and solution of prepared zirconium arsenate precipitate in a strong acid are discussed. Precipitation of zirconium arsenate was carried out at the boiling point in a solution with 10% free sulfuric acid and using sodium arsenate as precipitating agent (with 40: 1 ratio to zirconium). Elutions using hot 2% ammonium chloride solutions produced better results than elutions with hot or cold water. Ten to twelve elutions proved to be sufficient. Without boiling, zirconium precipitates as Zr(HAsO/sub 4/); following 1 hour of boiling it transforms into a more stable ZrAs/sub 2/O/sub 7/. Results of Zr precipitation in hydrochloric and nitric acid media were in good agreement. (R.V.J.)
