Foreword
GB/T 6730 "iron ore" is divided into dozens of parts.
This section GB/T 6730 Part 14.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part Replaces GB/T 6730.14-1986 "Iron ore chemical analysis atomic absorption spectrophotometric determination of calcium and magnesium" in calcium
Determination of part of this section compared with GB/T 6730.14-1986, in addition to editorial changes, the main technical changes are as follows.
--- Remove the original standard determination of magnesium content;
--- Increasing the normative references;
--- Modify the principle and instrument part of the statement;
--- Increased the requirements of safe operation of the instrument;
--- Modify the absorbance measurement and curve of the operation sequence;
--- Modify the data processing part of the statement;
--- Increased test report.
This part is proposed by China Iron and Steel Association.
This part of the National Iron Ore and Direct Reduced Iron Standardization Technical Committee (SAC/TC317) centralized.

3 principle
The sample was decomposed with hydrochloric acid-nitric acid and evaporated to dryness. The residue was treated with hydrofluoric acid, melted with sodium carbonate, and combined with the main liquid. In a certain acidity, with chlorine
Strontium as a release agent, at an atomic absorption spectrophotometer wavelength of 422.7nm, the use of air - acetylene flame, were measured.
4 reagent
Unless otherwise indicated in the analysis, the use of only approved analytical reagents and in line with GB/T 6682 provisions of distilled water or its purity phase
