Foreword

GB/T 11200 "high purity sodium hydroxide test method" is expected to be divided into the following three parts. --- Part 1. Determination of sodium chlorate o - tolidine spectrophotometry; --- Part 2. Determination of aluminum oxide content spectrophotometry; --- Part 3. Determination of calcium content by flame atomic absorption spectrometry. This section GB/T 11200 Part 2. This portion corresponds to ISO 6353-1. 1982 "General Methods Chemicals" GM9. Aluminum (in English), and ISO 6353-1. 1982 is equivalent to the degree of non-conformity. This Part replaces GB/T 11200.2-1989 "Ion-exchange membrane caustic soda in the aluminum oxide content of spectrophotometric law". This section compared with the GB/T 11200.2-1989 The main changes are as follows. --- Modify the standard name; --- Increasing the standard "foreword"; --- Modify the sample size (1989 Edition Chapter 6; edition 6.2); --- Modify the sample preparation solution (1989 edition, Chapter 6; edition 6.2); --- Modify the aluminum content is calculated (1989 edition, Chapter 9; Chapter 7 of this edition); --- Increase the "Test Report" section (see Chapter 9).
