Specifications --- 2nd Series" in R80 "hexacyanoferrate trihydrate Iron (Ⅱ) of potassium, "the degree of consistency is not equivalent. This standard replaces GB/T 1273-1988 "Chemicals hexacyanoferrate (Ⅱ), potassium (potassium ferrocyanide)", and GB/T 1273- The main changes compared to 1988 are as follows. --- Standard name changed to "trihydrate hexacyano iron (Ⅱ), potassium (potassium ferrocyanide)"; --- Increased traits (Chapter 3 of this edition); --- Water insoluble matter, chlorides, sulfates use chemical reagents common method for determining (1988 edition 4.2.1,4.2.2,4.2.3; edition The 5.4,5.5,5.6). The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee Chemistry Chemicals Branch (SAC/TC63/SC3) centralized. This standard was drafted. Sinopharm Chemical Reagent Co., Ltd. The main drafters of this standard. Chenhao Yun, Chen Hong. This standard was first published in 1977, in 1988, the first revision.
