Determination of chlorine, phosphorus and potassium in compound fertilizer products by energy dispersive X-ray fluorescence spectrometer EDX-9000B

Determination of chlorine, phosphorus and potassium in compound fertilizer products by energy dispersive X-ray fluorescence spectrometer EDX-9000B

Our company uses energy dispersive X-ray fluorescence spectrometer EDX9000B to detect chlorine, phosphorus and potassium content in compound fertilizer productsIt includes the following steps :1) Select different types and contents of compound fertilizer products as calibration samples, and accurately determine the content of chlorine, phosphorus and potassium;2) Use energy dispersive X-ray fluorescence spectrometer to determine the calibration sample of compound fertilizer with known chlorophosphate and potassium content, and determine the test conditions of chlorophosphate and potassium;3) The energy dispersive X-ray fluorescence spectrometer was used to test the compound fertilizer sample to be tested. According to the relationship between the X-ray fluorescence spectral intensity and the content of chlorine, phosphorus and potassium in the calibration working curve constructed by 2), the content of chlorine, phosphorus and potassium in the compound fertilizer sample to be tested was obtained. The invention can quickly determine the content of chlorophosphate and potassium in compound fertilizer, composite fertilizer, blended fertilizer and other products, and reduce the use of chemical reagents. The detection process is convenient and fast, the detection result is accurate and the consistency is good
