1 Scope

This section provides general requirements for flame atomic absorption spectrometry Carbide chemical analysis. Each of the criteria listed in a part table defines the method for determining the content of the following elements by flame atomic absorption spectrometry. Calcium, cobalt, chromium, iron, potassium, magnesium, manganese, molybdenum, sodium, nickel, titanium, vanadium.

2 Scope

This method is applicable to the following ranges. a) chromium, niobium, tantalum, titanium, tungsten, vanadium carbide; b) a mixture of the carbide metal bonding; c) Using the above-described various types of pre-sintered carbide production or sintered carbide; d) after complete removal of the coating containing coated carbide elements listed in Table 1. Table 1 GB/T 20255 and each element of each part number and scope of the appropriate section contains No part of the respective range of elements (mass fraction) /% GB/T 20255.1 Ca, K, Mg, Na 0.001 ~ 0.02 GB/T 20255.2 Co, Fe, Mn, Ni 0.01 ~ 0.5 GB/T 20255.3 Mo, Ti, V 0.01 ~ 0.5 GB/T 20255.4 Co, Fe, Mn, Mo, Ni, Ti, V 0.5 ~ 2 GB/T 20255.5 Cr 0.01 ~ 2 Note. The method can also be used chromium content range (mass fraction) was measured at 0.01% to 2% of iron, nickel, cobalt and manganese. Principle 3 Sample dissolution and flame atomic absorption spectrometry.

4 interfering elements

Using a similar matrix in the test solution and standard solution to minimize the influence of interference.

5 Reagents

Use only analytical reagent and double distilled water or equivalent purity water analysis. Note. The purity reagents required under certain circumstances.

6 Instruments

Conventional laboratory equipment and atomic absorption spectrometer. NOTE. All the instrument parameters should be selected so that the best instrument sensitivity. Proposed that a single element hollow cathode lamp. See recommended equipment requirements GB/T 20255.1 - 20255.5 of the corresponding portion. GB/T 20255.6-2008/ISO 7627/1. 1983 ......
