标准摘要
[中文适用范围]： 本标准规定了测定微量水溶性无机阴离子，如氟离子（F−）、氯离子（Cl−）、溴离子（Br−）、碘离子（I−）、亚硝酸根（NO2−）和肥料中的硫氰酸盐 (SCN−)。 [外文原描述]： ISO 20702:2017 specifies the ion chromatography method for the determination of microamounts of water soluble inorganic anions, such as fluoride (F − ), chloride (Cl − ), bromide (Br − ), iodide (I − ), nitrite (NO 2 − ) and thiocyanate (SCN − ), in fertilizers.
