| Abstract: | The main components of lime are CaO and MgO, in the production and transportation process, it is easy to absorb H2O and CO2 in the air, affecting the quality of lime, in the traditional detection method, CaO and MgO use EDTA titration method, the method in the detection process, it is inevitable to avoid the impact of CO2 in water on the results, in practical application, different laboratory detection nodes Results often vary greatly. In this experiment, the limestone standard sample was selected and burned it at 1000°C to obtain the quicklime standard sample. Li2B4O7 was used as the flux, and the molten glass sheet method was employed. The sample to flux ratio was 1:10, and 0.2 mL of 300 g/L NH4I solution was added as the release agent. The calibration sample was accomplished by melting at 1000°C for 10 min. In X-ray fluorescence spectrometer, spectral line interference was eliminated by spectral line correction, and matrix correction was carried out according to the empirical coefficient method to correct the effect of calcination in the sample on the results. A composition analysis method for CaO, MgO, SiO2, Al2O3, Fe2O3, TiO2, K2O, and Na2O in quicklime was established. Through the verification of the precision and accuracy of the method, it was proved that the results of the method could meet the needs of daily production quality monitoring. Through the method verification, the relative standard deviation of the detection results of different elements of the method is between 0.02%-4.11%. By comparing the certified standard samples with different methods, the result error is within the allowable range, which proves that the results of the method can meet the needs of daily production quality control. |
