Access to a comprehensive analysis of the literature, to determine the Ferric Sulfate titration analysis of titanium carbide, titanium program design, Ferric Sulfate Titration is a chemical analysis method,The principle is that of Fe3 + and of Ti3 + redox reaction, in order to consume the content of titanium in the amount of standard solution of sulfuric acid ferric ammonium conversion.Is usually the method of chemical analysis in the determination of the need to sample decomposition into a solution state, so the design of this program include the decomposition of the samples and determination of two parts. The article from said sample volume, sample decomposition, titration acidity, eliminate the concentration of the standard solution and interfering elements and other aspects of the design,Combination of existing methods of analysis and practical experience to determine a wide range of conditions range of parameters,Precision experiments and recovery of experimental design and the evaluation of the analysis methods established by the Experimental Institute. By this design to determine the approximate range of titanium carbide, titanium analysis of the determination of the parameters, the establishment of a full-titanium determination analysis program laid the foun
