- Scope
- This standard specifies ion chromatography for the determination of fluoride ions (F-), chloride ions (Cl-), phosphate ions (PO43-), nitrite ion (N02-), nitrate ion (N03-), sulfate ion (SO4 2-) method. This standard applies to industrial circulating cooling water and boiler water with fluorine ion content of 0.10mg/L~100.0mg/L; chloride ion content of 0.10mg/L~500.0mg/L; phosphate ion content of 0.10mg/L~100.0 mg/L Determination of nitrite ion content 0.10 mg/L~100.0mg/L; nitrate ion content 0.10mg/L~100.0mg/L; sulfate ion content 0.20mg/L~500.0mg/L range. This standard is also applicable to fluoride ions (F-), chloride ions (Cl-), phosphate ions (PO43) in surface water, groundwater and other industrial water. -), nitrite ion (N02-), nitrate ion (N03->), sulfate ion (SO4< Superscript 2->) Determination of plasma.
