CuSO4back titration method for the determination of aluminum content in experimental conditions of Al2O3Abstract: in this paper, aluminum as samples, using the CuSO4back titration method for the determination of aluminum content in Al2O3in the experimental condition of experimental conditions, including experiments in EDTA standard solution added, buffer solution HAc-NaAc content and PAN concentration of indicator, and changes in these experimental conditions for the determination of aluminum content in Al2O3, and controlled Pharmacopoeia method, the determination results with groo does not think ( G) method for inspection of questionable value, using the F test method to test its tightness, so as to probe into the method of optimal experimental words: three two aluminum oxide; aluminum; titration method; experimental conditions
