Summary This standard specifies the industrial circulating cooling water Na +, NH4 +, K +, Mg2 + and Ca2 + content determination. This standard applies to industrial circulating cooling water Na + content of 1. 00 mg/L ~ 50. 0 mg/L, NH4 + content of 1. 00 mg/L ~ 30. 0 mg/L, K + content of 1. 00 mg/L ~ 50. 0 mg/L, Mg2 + content of 1. 00 mg/L ~ 50. 0 mg/L and Ca2 + content 1. 00 mg/L ~ 50. 0 mg/L measurement range. If you exceed this range can be measured dilution within this range. This standard also applies to surface water, groundwater and other industrial water Na +, NH4 +, K +, Mg2 + and Ca2 + content determination.

Foreword

This corresponds to the standard ISO 14911.1998 "Water quality using ion chromatography testing water and wastewater soluble Li +, Na +, NH4 +, K +, Mn2 +, Ca2 +, Mg2 +, Sr2 + and Ba2 + method of "(in English), and the degree of consistency of non-ISO equivalent. This standard replaces GB/T 15454-1995 "industrial cooling water, sodium, ammonium, potassium, magnesium and calcium ions by ion chromatography." The main changes in the standards and GB/T 15454-1995, compared as follows. --- Increase in ion chromatography flow path diagram in the method of the feed; --- Added "5 interference." The Standard Appendix A, Appendix B, Appendix C are informative appendices. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee of Chemical Water Treatment Chemicals Branch (SAC/TC63/SC5) centralized. This standard is drafted by. Guangzhou City Special Pressure Equipment Inspection and Research Institute, CNOOC Tianjin Chemical Research & Design Institute. The main drafters of this standard. Zhou Guofu, Chen Tong Lin, Du Yuhui, Li Lin, Shao Hongqian. This standard was first published in 1995. Industrial circulating cooling water, sodium, ammonium, potassium, magnesium and Calcium ion chromatography

1 Scope

This standard specifies the industrial circulating cooling water Na +, NH4 +, K +, Mg2 + and Ca2 + content determination. This standard applies to industrial circulating cooling water Na + content of 1.00mg/L ~ 50.0mg/L, NH4 + content of 1.00mg/L ~ 30.0mg/L, K + content of 1.00mg/L ~ 50.0mg/L, Mg2 + content of 1.00mg/L ~ 50.0mg/L and the content of Ca2 + 1.00mg/L ~ 50.0mg measurement/L range, if out of this range, can be diluted and analyzed within this range. This standard also applies to surface water, ground water and other industrial water in Na +, NH4 +, K +, Mg2 + and Ca2 + was measured content.

3 Terms and Definitions

The following terms and definitions apply to this standard. 3.1 By ion exchange separation of ionic components, and then use the appropriate detector, it is a branch of high-performance liquid chromatography. 3.2 Before separation column placed to protect the separation column against particulate matter or irreversible contamination of impurities such reservations. 3.3 According to the detected ion retention characteristics, it will be detected prior to detection of the ion exchange column separation. 3.4 After the guard column is connected in one or more separation columns for separating the composition of a series of test ion analysis system. All the pillars of the series The total capacity of the column analytical column with the contribution. 3.5 Installed between the analytical column and a detector for detecting the response lotion reduce leaching of ionic components, in response to detection of an increase of the detected ion, A special device thus improving the signal to noise ratio. 3.6 Phase flow of ions, the sample carrier through the analytical column.
