《GB/T 14642-2009工业循环冷却水及锅炉水中氟、氯、磷酸根、亚硝酸根、硝酸根和硫酸根的测定 离子色谱法》由TC63(全国化学标准化技术委员会)归口,TC63SC5(全国化学标准化技术委员会水处理剂分会)执行,主管部门为中国石油和化学工业联合会。
本标准规定了离子色谱法测定工业循环冷却水及锅炉水中氟离子(F- )、氯离子(Cl- )、磷酸根离子
(PO43- )、亚硝酸根离子(NO2- )、硝酸根离子(NO3- )、硫酸根离子(SO42- )的方法。
本标准适用于工业循环冷却水及锅炉水中氟离子含量0.10 mg/L~100.0 mg/L;氯离子含量0.10mg/L~500.0mg/L;磷酸根离子含量0.10mg/L~100.0mg/L;亚硝酸根离子含量0.10mg/L~100.0mg/L;硝酸根离子含量0.10mg/L~100.0mg/L;硫酸根离子含量0.20mg/L~500.0mg/L范围的测定。
本标准也适用于地表水、地下水及其他工业用水中氟离子(F- )、氯离子(Cl- )、磷酸根离子(PO43- )、亚硝酸根离子(NO2- )、硝酸根离子(NO3- )、硫酸根离子(SO42- )等离子的测定。
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.
