Foreword
GB/T 8570 "Determination of liquid anhydrous ammonia method" is divided into seven parts.
- Part 1. Adoption of laboratory samples;
- Part 2. Ammonia content;
- Part 3. Residue content weight method;
- Part 4. Residual content volumetric method;
- Part 5. Moisture Fisher Fischer;
- Part 6. Oil content gravimetric and infrared absorption spectroscopy;
- Part 7. Iron content - phenanthroline spectrophotometric method.
This part is part 4 of the GB/T 8570.
This part of the replacement of GB/T 8570.4-1988 "liquid anhydrous ammonia residue content determination capacity method."
The main differences between this edition and the previous edition are.
Preparation and calibration of reagent solutions, standard titration solutions, etc. Execution of HG/T 2843 standards;
--- increase the contents of the security warning;
- standardize the standard format according to the new requirements.
This section is proposed by the China Petroleum and Chemical Industry Association.

Determination of liquid anhydrous ammonia
Part 4. Residue content volumetric method
WARNING - Personnel using this standard should have practical experience in formal laboratory work. This standard does not indicate all possible security questions
question. It is the responsibility of the user to take appropriate safety and health measures and to ensure compliance with the conditions of the relevant national laws. Liquid anhydrous ammonia high
Toxic to the skin, mucous membranes and eyes are corrosive, contact can cause severe burns. Operation should be properly protected.
1 Scope
This part of GB/T 8570 specifies the capacity measurement method for liquid anhydrous ammonia (liquid ammonia) residue content.
2 normative reference documents
The terms of this document are the terms of this part by reference to this part of GB/T 8570. Any reference to the date of the document,
Any subsequent amendments (not including corrigenda) or revisions shall not apply to this part, however, it is encouraged to enter into an agreement under this Part
The parties study whether the latest versions of these files can be used. For undated references, the latest edition applies to this section.
HG/T 2843 chemical analysis of chemical fertilizers commonly used standard titration solution, standard solution, reagent solution and indicator solution
3 principle
After evaporating the liquid ammonia sample at room temperature, the volume of the evaporated residue was read and the residue was evaporated in the presence of an indicator in the presence of a sulfuric acid standard solution
Ammonia in the material, according to the formula, calculate the residue content.
4 reagents and materials
The reagents, solutions and water used in this part shall comply with the requirements of HG/T 2843 when not specified and formulated.
4.1 Sulfuric acid standard titration solution, c (12H2SO4
) = 0.1 or 1 mol/L;
4.2 methyl red indicator solution, 1g/L.
5 instruments
5.1 General laboratory equipment;
5.2 Li Senke acceptor, see Figure 1, the total volume of not less than 500mL, the upper part of the 10mL, the lower tube volume of 1.00mL, the smallest
0.05 mL.
