What this standard covers

This standard specifies the determination of industrial cooling water and boiler water fluoride ion (F-) ion chromatography, chloride ions (C1-), phosphate ion (PO43-), nitrite (NO2-), nitrate ion (NO3-), sulfate ions (SO4-) method. This standard applies to industrial cooling water and boiler water fluoride content 0. 10 mg/L ~ 100. 0 mg/L, chloride ion content of 0. 10 mg/L ~ 500. 0 mg/L, phosphate ion content of 0. 10 mg/L ~ 100. 0 mg/L, sulfate ion content of 0. 20 mg/L ~ 500. 0 mg/L measurement range, nitrate ion content of 0. 10 mg/L ~ 100. 0 mg/L, nitrite ion content of 0. 10 mg/L ~ 100. 0 mg/L. This standard also applies to surface water, groundwater and other industrial water fluoride ion (F-), chloride ions (C1-), phosphate ion (PO43-), nitrite (NO2-), nitrate ion (NO3-), sulfate ion (SO42-) determination of plasma.
