| titleOfInvention | A kind of rapid determination method of aluminum content in ferrovanadium |
| abstract | The invention provides a method for rapid determination of aluminum content in ferrovanadium, comprising the following steps: (1) preparing a sample solution: weighing 0.1000-0.2000 g of ferro-vanadium sample, placing it in a beaker, adding 2-5 mL of distilled water to wet the sample ; Then add 15-30 mL of nitric acid solution to it, heat to dissolve the sample; after the sample is completely dissolved, set the volume to 100 mL, that is; (2) prepare aluminum standard solution; (3) draw standard curve; (4) sample determination : Use an inductively coupled plasma atomic emission spectrometer to measure the absorbance of the sample solution under the same conditions as in step (3), then calculate the concentration of aluminum in the sample solution according to the standard curve drawn in step (3), and then calculate the vanadium Aluminium content in iron. The method provided by the invention is highly accurate, simple to operate, and improves the inspection efficiency. |
