GB/T 3286 "Methods for chemical analysis of limestone and dolomite" is divided into nine sections.
--- Part 1. calcium oxide and magnesium oxide content complexometric titration and flame atomic absorption spectrometry;
--- Part 2. Determination of silica content of silicon molybdenum blue spectrophotometric method and perchloric acid dehydration gravimetric method;
--- Part 3. Determination of alumina content of chromium azure S spectrophotometric and complexometric titration;
--- Part 4. Determination of iron oxide content of phenanthroline spectrophotometric method and the flame atomic absorption spectrometry;
--- Part 5. Determination of periodate oxidation of manganese oxide spectrophotometry;
--- Part 6. Determination of phosphorus content of phosphorus molybdenum blue spectrophotometric method;
--- Part 7. Determination of sulfur content tube furnace combustion - potassium iodate titration method, high-frequency combustion infrared absorption method and barium sulfate gravimetric method;
--- Part 8. Determination of the weight loss on ignition;
--- Part 9. Determination of carbon dioxide content of the caustic asbestos absorption gravimetric method.
This section GB/T 53286 Part of.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part replaces GB/T 3286.5-1998 "limestone, dolomite chemical analysis of manganese oxide content determination."
This section compared with the GB/T 3286.5-1998, the main technical changes are as follows.
--- The standard name be changed to "chemical analysis of limestone and dolomite - Part 5. Determination of oxygen periodate oxidation of manganese content
Spectrophotometry ";
--- Normative references canceled the reference standard reign, and adds some reference standards;
--- Carried out jointly between laboratory precision test statistics obtained by the repeatability limit (r) and reproducibility limit R instead of "allowable difference";
--- Change the part of the text expression.
This part is proposed by the China Iron and Steel Association.
This part of the National Steel Standardization Technical Committee (SAC/TC183) centralized.
This section is drafted. Wuhan Iron and Steel (Group) Corporation, Metallurgical Industry Information Standards Institute.

Those who have the responsibility to take appropriate safety and health practices and to ensure compliance with the conditions relevant national regulations.
1 Scope
GB/T 3286 provisions of this part of the spectral oxidation with periodate spectrophotometric determination of manganese oxide content.
This section applies to limestone and dolomite - The determination of manganese oxide (MnO in volume), but also applies to the metallurgical manganese oxide containing lime
Determination of the amount. Measurement range (mass fraction). manganese oxide content of 0.005% to 0.50%.

Principle 3
High temperature burning sample decomposition with hydrochloric acid, perchloric acid, perchloric acid smoke. In phosphoric acid medium, under heating conditions with periodate dicarboxylic
Seven-valent manganese oxidation of manganese, the absorbance is measured in a spectrophotometer at a wavelength of 525nm.
4 Reagents
4.1 Analysis Unless otherwise stated, use only reagents of recognized analytical grade and in line with GB/T 6682 provisions or distilled water three or more
Equivalent purity water.
4.2 hydrochloric acid, 11.
Perchloric acid 4.3, ρ = 1.67g/mL.
4.4 phosphoric acid, 11.
4.5 sodium (potassium) solution, 20g/L.
Weigh 10g sodium (potassium) in the beaker, add 300mL water, add 20mL of nitric acid (11), warmed to dissolve, dilute with water to
500mL, and mix.
Note. The preparation of high potassium iodate solution when cooled to room temperature, low temperature may have a little crystal precipitation, does not affect the results.
