    • PURPOSE: A method for simultaneously analyzing hexavalent chromium and trivalent chromium with ion chromatography is provided to analyze components rapidly and correctly in a sample. CONSTITUTION: A method for simultaneously analyzing hexavalent chromium and trivalent chromium includes the following steps of: separating mixed components of the hexavalent chromium and the trivalent chromium with a mixed solvent; combining the trivalent chromium with a chelating agent by adding a moving phase of which pH is 6.5-6.8; performing chromatography analysis by injecting the moving phase to an ion chromatography(IC) column; converting the hexavalent chromium to a fluometric reagent; and separating absorbance of the trivalent chrome with a UV-absorption photometer.
    • 目的:提供用离子色谱法同时分析六价铬和三价铬的方法,用于在样品中快速,准确地分析组分。 构成:同时分析六价铬和三价铬的方法包括以下步骤:用混合溶剂分离六价铬和三价铬的混合组分; 通过添加pH为6.5-6.8的运动相将三价铬与螯合剂组合; 通过将移动相注入离子色谱(IC)柱进行色谱分析; 将六价铬转化成流感试剂; 并用紫外线吸收光度计分离三价铬的吸光度。
