A simple accurate method has been developed for the determination of neodymium in the Al-Nd-Ti alloys. The sample wasdissolved in sulphuric acid (1+1) and the neodymium was separated from titanium, aluminum etc. through precipitation in an oxalicacid solution with pH 1. 5~2. 0. The neodymium content was calculated through weighing the neodymia obtained by calciningneodymium oxalate. This method has been successfully applied to routine analysis. The recovery of neodymium is 98. 5%~101. 3%.Relative standard deviation is 1. 34%.
