本文报道了环境水中亚硝酸与硝酸根离子迅速、简便的高速液相色谱测定方法。高速液相色谱仪是日本分光制型,带UVIDEC 100Ⅱ型紫外分光检测器,不锈钢分离柱25 cm×4.6 mm。定量方法:水样经孔径0.45μm的薄膜过滤器过滤,用微量注射器取其5～20μl注入色谱仪。按附表所示操作条件进行测定,以亚硝酸与硝酸根离子在不同浓度时峰高制备标准曲线,求得样品含量。在0～50 ng范围内亚硝酸与硝酸根离子
This paper reports the rapid and simple method for the determination of nitrite and nitrate in ambient water by high performance liquid chromatography. High-speed liquid chromatography is Japan’s spectrophotometry, with UVIDEC 100 Ⅱ UV spectrophotometer, stainless steel separation column 25 cm × 4.6 mm. Quantitative method: The water sample is filtered through a membrane filter with a pore size of 0.45 μm and injected into the chromatograph with a micro syringe of 5 to 20 μl. Measured according to the operating conditions shown in the table to nitrite and nitrate ions at different concentrations peak preparation of standard curve obtained sample content. Nitrite and nitrate ions in the 0-50 ng range
