GB/T 11848.1-2008 Part 1 stipulates the determination of uranium in uranium ore condensate by ferrous sulfate reduction-potassium dichromate Titrimetric method. It is suitable for all kinds of uranium ore condensate samples. The method first uses ferrous sulfate to reduce high-priced uranium, and then titrates the reduced uranium with potassium dichromate, and calculates the uranium content according to the amount of potassium dichromate. The standard specifies the required instruments, such as Burette, etc., and specifies the preparation of reagents. Detailed description of Sample Handling steps, including the details of dissolving and reducing the ore condensate. Standardized titration process and end point judgment. According to this standard, the uranium content can be accurately determined, providing key data for uranium resource evaluation and nuclear industry production.
