GB/T 1511-2006 《Manganese ores - Determination of calcium and magnesium contents - EDTA titrimetric method》 Related products

GB/T 1511-2006 The EDTA Titrimetric method is used to determine the content of calcium and mg in manganese ores. It is suitable for all kinds of manganese ore samples. The principle is to use EDTA to complexate with calcium and mg ions. The standard specifies the required instruments, such as Burette, etc., and specifies the selection and preparation of reagents. Describe the steps of Sample Handling in detail, including dissolving and eliminating the influence of interfering ions. Standardize the titration operation process, such as titrant addition speed, indicator use and end point judgment. According to this standard, the calcium and mg content in manganese ores can be accurately determined, providing important data basis for manganese ore mass evaluation, smelting process formulation and product performance control.
