Foreword

GB/T 10267 "Method for analysis of calcium metal" is divided into five parts. --- Part 1. Determination of chlorine chloride ion selective electrode method; --- Part 2. Spectrophotometric determination of trace amounts of silicon; --- Part 3. Direct determination by atomic absorption spectrophotometry of iron, nickel, copper, manganese, magnesium; --- Part 4. 8-quinolinol - chloroform extraction spectrophotometric determination of aluminum; --- Part 5. Distillation - Nessler reagent spectrophotometric determination of nitrogen. This section GB/T Part of 310,267. This Part replaces GB/T 10267.3-1988 "calcium metal analysis by atomic absorption spectrometry direct determination of iron, nickel, copper, manganese, magnesium." This section compared with the GB/T 10267.3-1988, the main differences are as follows. --- Increasing the normative references; --- Like the hydrochloric acid solution of nitric acid to dissolve the sample; --- The self-made standard stock solution to a standard solution; --- Adjust the measurement range; --- Adjust the concentration of the standard solution and the sample solution. This part is proposed by the China National Nuclear Corporation. This part of the National Nuclear Energy Standardization Technical Committee (SAC/TC58) centralized. This section was drafted by. China North Nuclear Fuel Limited. The main drafters of this section. Helen Feng, Li Aijun, Zhao Haisheng, late new country. This part of the standard replaces the previous editions are. --- GB/T 10267.3-1988. Calcium metal analysis Part 3. Direct determination by atomic absorption spectrophotometry Iron, nickel, copper, manganese, magnesium
