Determination of Aluminum Trioxide Content in Dolomite Used in the Glass Industry by Chromazurol S Spectrophotomete
In this paper,a method for the determination of trace aluminium in dolomite for glass industry by chromium azure S spectrophotometer is described.On the basis of the experiment of sufficient conditions,the optimum analysis and determination conditions are determined,and the interference of coexisting elements is explained in theory and verified by experiments.The results showed that the concentration of Al 2O3 in the range of 0～0.5 mg/mL was in accordance with Lambert's law,the linear correlation coefficient of the standard curve was 0.9996,the standard deviation of the method was 0.003%～0.008%,and the relative standard deviation was 1.04%～3.95%.
