Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 14640-2008 "Determination of potassium and sodium content in industrial circulating cooling water and boiler water," and GB/T 14640- 2008 compared to the main technical changes are as follows. --- Modify the static method for the potential method (see 6.2,.2008 version 5.2); --- Increasing the flame emission spectrometry method for the determination of potassium and sodium (see Chapter 7); --- Added test report (see Chapter 8). This standard uses the redrafted law reference ISO 9964-1.1993 "Determination of water quality sodium and potassium Part 1. Atomic Absorption Spectrometry Determination of sodium ", ISO 9964-2.1993" Water quality - Determination of sodium and potassium - Part 2. Determination of potassium by atomic absorption spectrometry ", ISO 9964-3. 1993 "Determination of water quality sodium and potassium Part 3. Flame emission spectrometric determination of sodium and potassium" preparation, and ISO 9964-1.1993, ISO 9964-2.1993, ISO 9964-3.1993 The degree of consistency is not equivalent. This standard proposed by the China Petroleum and Chemical Industry Federation.
