DETERMINATION OF PHOSPHORUS IN V-N ALLOY

Trace phosphorus in V-N alloy was determined by beryllium salt coprecipitation—molybdenumblue spectrophotometry. This method was proved to have good precision and veracity. The low limit of determination is 0.001 6%, which completely satisfy the analytical request. The method is successfully applied to the determination of phosphorus in V-N alloy and the determining results are satisfying.
