Determination of total organic carbon in limestone1 ScopeThis standard specifies the three methods of quantitative determination of total organic carbon in limestone. This standard applies to the determination of total organic carbon in calcareous materials such as limestone.2 Normative referencesThe following documents for the application of this document is essential. For dated references, only the dated version applies to this article Pieces. For undated references, the latest edition (including all amendments) applies to this document. GB/T 2007.1 bulk mineral products sampling, sample preparation General manual sampling method GB/T 6682 analytical laboratory water specifications and test methods3 test the basic requirements3.1 The number of tests and requirements The number of tests for each test is defined as two and the absolute difference between the two tests is within the limit of repeatability (see Chapter 10) The average of the results indicates the measurement result. 3.2 Quality and result representation Mass units with "grams (g)", accurate to 0.0001g. Unless otherwise stated, the analytical results are expressed in% by mass and the analytical results are expressed in% to two decimal places. 3.3 blank test The test results obtained were corrected by not adding the test sample, following the same analytical procedure and using the same reagent amount.4 Reagents and materials4.1 General Reagents used should be no lower than analytical grade, unless otherwise stated. The reagent used for calibration should be the reference reagent. The water used should not be less than GB/T 6682 provisions of the three water requirements. The density of commercially available concentrated liquid reagents listed in this standard refers to the density (ρ) of 20 ° C in grams per cubic centimeter (g/cm3). In chemical analysis, the acid used, who did not note concentration refers to the commercially available concentrated acid. Reagent dilution is expressed in terms of volume ratio, for example, hydrochloric acid (1 2) indicates that 1 part by volume of concentrated hydrochloric acid is mixed with 2 parts by volume of water. 4.2 Hydrochloric acid (HCl) 1.18g/cm3 ~ 1.19g/cm3, the mass fraction of 36% to 38%. ...... |
