Flame atomic absorption spectrometry Law "and GB/T 2467.3-1996" Pyrites and concentrate - Determination of lead content - Part 3. EDTA volumetric method ", these two standard It merged into a quasi-standard, divided into two methods. The standard proposed by China Petroleum and Chemical Industry Association. This standard is under the jurisdiction of Chemical Industry Standardization Technical Committee chemical mine. This standard was drafted. even in the blue sea and Design Institute. The main drafters of this standard. the king of peace, Zhang Xiaomei. This standard replaces the standards previously issued as follows. --- GB/T 2467.1-1996; --- GB 2467-1981, GB/T 2467.3-1996.
