本文提出了借助电子顺磁共振光谱测定分选精矿中高岭石的数最来分析和监控其质量的新方法。这种方法的依据是,在高岭石的电子顺磁共振光谱中,所记录到的稳定根的狭窄信号在g=2的区域内。g=2是高岭石的特征值。测定被测样品的电子顺磁共振信号的强度(图1),并与由纯高岭石组成的标准样品对比,可确定被测样品中高岭石的百分含量。因为现代电子顺磁共振光谱仪的灵敏度很高,所以,试验所需物料量不大
In this paper, we propose a new method to analyze and monitor the quality of kaolinite by electron paramagnetic resonance spectrometry. The basis of this method is that in the electron paramagnetic resonance spectrum of the kaolinite, the narrow signal of the stabilized root recorded is in the region of g = 2. g = 2 is the eigenvalue of kaolinite. The intensity of the electron paramagnetic resonance signal of the sample being measured (Figure 1) is determined and compared to a standard sample consisting of pure kaolinite to determine the percentage of kaolinite in the sample being tested. Because of the high sensitivity of modern electronic paramagnetic resonance spectroscopy, so the amount of material required for the test is not large
