Foreword
This standard and ISO 6353-2. 1983 "Reagents for chemical analysis - Part 2. Specification 1 of this series," The R25 "KI" consistency
Not equivalent.
This standard replaces GB/T 1272-1988 "chemical reagents potassium iodide," compared with the GB/T 1272-1988 The main changes are as follows.
--- AR content specifications from 98.5% up to 99.0%, chemically pure specifications from 98.0% up to 98.5% (1988 edition
3.1, the first edition chapter 4);
--- The pH value, Clarity test, water-insoluble, chloride and bromide, sulfate, phosphate, total nitrogen, iron, arsenic, heavy metals switch
Chemicals General Method (1988 version 4.2,4.3.1,4.3.2,4.3.4,4.3.5,4.3.6,4.3.7,4. 3.11
4.3.12,4.3.14, Excerpts 5.4,5.5,5.6,5.8,5.9,5.10,5.11,5.15,5.16 , 5.18).
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. Zhejiang Haichuan Chemical Co., Ltd.
The main drafters of this standard. Zheng Jianhua, Zhang Huaiyi.
This standard was first published in 1962, the first revision in 1977; the second revision in 1988.
