Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 218-1996 "Determination of carbonate carbon dioxide content in coal", compared with GB/T 218-1996, except Editorial changes, the main technical changes are as follows. - Increased positive pressure supply test method (see 5.2, 6.2); - an increase in the accuracy of the test system (see 6.1.4, 6.2.4); --- Added chapter on the test report (see Chapter 9). This standard uses the re-drafting method to modify ISO 925..1997 "Solid fossil fuels Carbonate Carbon content determination method Weight law". This standard has a greater structural adjustment compared to ISO 925..1997, which is listed in Appendix A and the ISO 925..1997 A comparison of the numbers. There are technical differences compared to ISO 925..1997, and the terms involved in these differences have been passed on their outer margins The vertical single line (︱) of the blank position is marked, and Appendix B gives a list of the corresponding technical differences and their causes. This standard is proposed by China Coal Industry Association. This standard is under the jurisdiction of the National Coal Standardization Technical Committee (SAC/TC42). The drafting unit of this standard. Coal Science and Technology Research Institute Co., Ltd. Detection Branch. The main drafters of this standard. Wang Qiuxiang, Wang Run Ye, Yang Ni. This standard replaced the previous version of the standard release. GB 218-1963, GB 218-1983, GB/T 218-1996. Determination of carbonate carbon dioxide content in coal

1 Scope

2 normative reference documents

The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. Rules for the analysis of coal - General test methods GB/T 6682 Analytical laboratory water specifications and test methods

3 method summary

After the coal sample is treated with hydrochloric acid, the carbonates in the coal decompose and precipitate the carbon dioxide gas. The precipitated carbon dioxide gas is filled with alkali asbestos (or Soda lime) absorbance of the absorber, according to the increase in the quality of the absorber to calculate the carbonate carbon dioxide content of carbon dioxide.
