Analysis principle of X-ray fluorescence spectrum based on new semiconductor II
The atoms of the elements in the sample are excited by high-energy radiation, which causes the transition of the inner electrons and emits X-rays with certain energy. The X-ray detector with certain energy resolution is used to detect various energy characteristic X-rays emitted by the measured elements in the sample. According to the energy of the detector output signal, we can know which elements are contained in the sample and make qualitative analysis. According to the energy intensity of the detector output signal, compared with the known standard sample intensity, the content of this element can be known, that is, quantitative analysis can be carried out.
Colorimetry-spectrophotometry
Based on the unique standard reagent reacting with some elements (ions) in the soil to generate colored compounds, the content of the components to be detected is determined by measuring the light absorption intensity of the colored substance solution with a spectrophotometer by using Lambert-Beer law.
3 The accuracy of performance advantage judgment is ≤ 15%.
X-ray fluorescence method based on a new semiconductor detector is used for rapid detection, which can accurately detect up to 15 kinds of heavy metal elements such as titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, arsenic, selenium, cadmium, antimony, mercury and lead at one time, and the results can be obtained in 3~30S.
Using a unique standard reagent, various parameters such as cyanide, fluoride, organic matter, PH value, nitrogen, phosphorus and potassium in soil can be obtained quickly within 30 minutes.
It has complete functions. In addition to detecting heavy metals, cyanide, fluoride, organic matter, PH value and nitrogen, phosphorus and potassium, the new semiconductor detector integrated in the equipment can also directly detect radioactive substances in the soil.
Convenient and portable, small in size, light in weight, easy to carry, simple in sample preparation, movable and easy to test in situ.
Application fields: government environmental protection and agricultural institutions, laboratories of colleges and universities, environmental monitoring and management companies such as soil remediation and mining of heavy nonferrous metals (including associated minerals), smelting industry, coal mining area, lead-containing battery industry, leather and its products industry, chemical raw materials and chemical products manufacturing involving heavy metals, electroplating industry, etc.
