Uncertainty Evaluation in Determination of Fluorine Content in Copper Concentrate by Fluoride Ion-Selective Electrode Method
According to the requirements of GB/T 601-2012 on the uncertainty of chemical analysis and measurement by national standard method,the uncertainty components of fluorine determination in copper concentrate by fluoride ion meter were evaluated in detail.The contribution values are arranged in order from the uncertainty component brought by the balance of one ten thousandth when weighing the sample,the uncertainty component brought by the constant volume of a 100 mL volumetric flask and the ambient temperature,the uncertainty component brought by the fitting of fluoride ion working curve and the uncertainty component brought by the uniformity of the sample.
