AN72751: Determination of Anionic Impurities in Sulfuric Acid using Ion Chromatography (Method 1)
Description
This study demonstrated that anionic impurities such as fluoride, chloride, nitrite, bromide, and nitrate can be determined accurately in sulfuric acid using Method 1. Method 1 uses a Dionex IonPac AS19 HC-4 µm column with hydroxide eluent, which is ideal for separating a wide range of inorganic anions with high sensitivity.The anionic impurity phosphate can be determined accurately in sulfuric acid using Method 2. Method 2 uses a Dionex IonPac AS23-4μm column with carbonate eluent, which is ideal for phosphate because it elutes before sulfate. This record shows Method 1.| Market: | Chemical; Electronics & Semiconductors |
