| Abstract: | This paper is about the comparative experiment between the methods of zinc salt back titration and copper salt back titration adopted to determine the amount of aluminum oxide in aluminum hydroxide and that of the national standard about the ＂aluminum hydroxide＂.At the same time,the paper introduces respectively the basic principles,the test steps,the test process and the points for attention in this experiment of the back titration methods of zinc salt and copper salt.Finally,a recovery test has been carried out and the experiment result shows that these three methods can be exchanged for one another. |
