This part replaces GB/T 4333.7-1984 "silicon iron chemical analysis method chromatographic separation of barium sulfate gravimetric method for determination of sulfur". This section
Compared with GB/T 4333.7-1984, the main technical changes are as follows.
--- Increased scope (see Chapter 1);
--- Added normative references (see Chapter 2);
--- Revised the way in which the test passes through the mesh (see Chapter 4 of 3.4, 1984);
--- Increased the number of measurements (see 3.5.1);
--- Increased the determination and representation of the results of the analysis (see 3.6.2);
--- Added Method 2 Infrared Absorption Method (see Chapter 4);
--- Increased the content of the test report (see Chapter 5);
--- Added the normative appendix "Flowchart of Acceptance of Test Analysis Results Acceptance Procedures" (see Appendix A).
This part was proposed by the China Iron and Steel Association.
This part is under the jurisdiction of the National Iron and Iron Alloy Standardization Technical Committee (SAC/TC318).

3.1 Principle
The sample was dissolved in nitric acid and hydrofluoric acid in a bromine solution, and smoked with perchloric acid, and the salt was dissolved in water and then filtered. The filtrate passes through the activated alumina color
The column was removed, most of the interfering elements were removed, the sulfate ions on the chromatography column were eluted with dilute ammonium hydroxide, and then the sulfur was determined by the barium sulfate gravimetric method.
3.2 Reagents and materials
In the analysis, unless otherwise stated, only the reagents confirmed as analytically pure are used, and the test water is the third and third grades specified in GB/T 6682.
Distilled water, deionized water or water of equivalent purity.
