A Probe into the Experimental Conditions for Determining the Al2O3 Content in Gastropine by Applying the CuSO4 Back Titration : Using Gastropine as specimen, this paper probes into the experimental conditions for determining its Al2O3 content by applying the CuSO4 back titration method. The experimental conditions include the titration volume of EDTA standard solution, the amount of HAc-NaAc buffer solution and PAN titration indicator to be used, and the variation of these experimental conditions to determine the Al2O3 content in Gastropine. With reference to the pharmacopeia method, the suspicious values of the results were tested by Grubbs’ (G) test method and the compactness was tested by the F test method, so as to find out the best experimental condition of this method. Key words: Gastropine; Al2O3; back titration method; experimental conditions 【英语牛人团】
