| Abstract: | According to the second section of the pharmacopoeia of PRC(2010 edition),this paper detects content of calcium oxide in magnesium oxide with the method of EDTA complexometric titration.Through evaluating different uncertainty components in the assaying process,this paper figures out the uncertainty during the process,assessing synthetic standard and expansion uncertainty.This uncertainty evaluation methodology has great practical utility in the work of measuring the content of calcium oxide in magnesium oxide with the method of EDTA complexometric titration. |
