Foreword

This standard corresponds to ASTMD4327.2003 "Standard Test Method for Determination of anions in water chemical suppression Ion Chromatography" (English Edition), and ASTMD4327.2003 is non-equivalent. This standard replaces GB/T 14642-1993 "industrial circulating cooling water and boiler water, fluoride, chloride, phosphate, nitrite, nitrate and Sulfate by ion chromatography. " The main changes in the standards and GB/T 14642-1993, compared as follows. --- Given 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, Du Yuhui, Zhuzhuan Jun, Xie Haiyuan, Bai Ying. This standard was first published in 1993. Industrial circulating cooling water and boiler water Fluorine, chlorine, phosphoric acid, nitrite, nitrate and Determination of sulfate ion chromatography

1 Scope

This standard specifies the Ion Chromatography industrial circulating cooling water and boiler water fluoride ions (F-), chlorine ion (Cl-), phosphate ion (PO43-), nitrite (NO2-), nitrate ion (NO3-), sulfate ion (SO42-) method. This standard applies to industrial cooling water and boiler water fluoride content of 0.10mg/L ~ 100.0mg/L; chloride ion content 0.10mg/L ~ 500.0mg/L; phosphate ion content of 0.10mg/L ~ 100.0mg/L; nitrite ion content of 0.10mg/L ~ 100.0mg/L; a nitrate ion content of 0.10mg/L ~ 100.0mg/L; a sulfate ion content 0.20mg/L ~ 500.0mg/L range Determination. This standard also applies to surface water, ground water and other industrial water fluoride ion (F-), chlorine ion (Cl-), phosphate ion (PO43-), nitrite (NO2-), nitrate ion (NO3-), sulfate ion (SO42-) plasma was measured.
