Abstract

The invention discloses a method for detecting content of iron in photovoltaic glass based on X-ray fluorescence energy spectrum, belonging to the technical field of detection. The method comprises the following steps of: selecting a representative photovoltaic glass sample, and manufacturing a calibration sample after the value of the iron content achieves constant by using a flame atomic absorption spectrometry, so that a problem that a standard sample in photovoltaic glass iron content measurement is in shortage is solved; measuring the calibration sample with constant photovoltaic glass iron content on an X-ray fluorescence energy disperse spectroscopy; establishing a calibration curve of the content of the iron in the photovoltaic glass, which is measured by adopting the X-ray fluorescence energy spectrum method; measuring the content of the sample in the photovoltaic glass sample by adopting the established calibration curve and the X-ray fluorescence energy disperse spectroscopy under a working condition the same as that in measuring the calibration sample. According to the method provided by the invention, the relative standard deviation (n =11) of the iron content measurement is between 4.5% and 9.0%, and the method is precise and reliable. The method is applied to analyzing a photovoltaic glass practical sample, the measured result is consistent with the analyzed result of the soda-lime-silica glass chemical analysis method of the national standard method GB / T1347-2008, and the working efficiency is more than 50 times that of the national standard method GB / T1347-2008, so that the requirements of quickly analyzing large-scale samples can be satisfied.

Description

technical field [0001] The invention relates to a detection method for determining the iron content in photovoltaic glass based on X-ray fluorescence energy spectroscopy (EDXRF), specifically an analysis method for rapidly and quantitatively determining the iron content in photovoltaic glass with an X-ray fluorescence energy spectroscopy instrument, which belongs to the detection method technology field. Background technique [0002] With the development of industry and the increase of human activities, human consumption of energy is increasing day by day, while underground non-renewable mineral energy is becoming increasingly scarce, and the contradiction between energy supply and demand is increasingly intensified. Energy issues have become one of the key issues affecting human survival and development. . Not only that, but the greenhouse gases produced by the burning of fossil energy accelerate the pace of global warming and cause various natural disasters to occur frequ...
