GB/T 5686.1-2008 《Ferromanganese，ferromanganese-silicon, nitrogen-bearing ferromanganese and manganese metal - Determination of manganese content - Potentiometric method and titrimetric mothod after ammonium nitrate & perchloric acid oxidation》 Related products

GB/T 5686.1-2008 provides three methods to determine the manganese content of ferromanganese and other materials. Potential Titrimetric method determines the end point by monitoring the change of potential; ammonium nitrate, perchloric acid oxidation Titrimetric method uses oxidation reduction reaction to titrate manganese after oxidation. This standard applies to products such as ferromanganese and manganese silicon alloys. Clarify the required instruments, such as Potentiometric titrator, Burette, etc., and specify the preparation of reagents. Detailed description of Sample Handling steps, including dissolve oxidation operations. Standardize three titration processes and end point judgment. According to this standard, the manganese content can be accurately determined, providing key data for product mass evaluation and control of manganese addition in steel smelting, and helping steel and related industries to produce.
