摘    要:本文通过实验确定了一种检测亚硝酸根含量试纸的制备方法。通过实验确定了试纸的材料和显色剂,并对显色剂制备过程中的影响因素进行了分析.实验结果表明:定性中速滤纸可以作为亚硝酸根试纸的材料;含有4-氨基苯磺酰胺和N-1-萘基乙二胺盐酸盐的显色剂A及含有1:1的α-萘胺溶液和对氨基苯磺酸溶液的显色剂B,按1:1混合后可以作为显色剂;通过应用实验表明,亚硝酸根试纸具有体积小、便于携带、检测方便、成本低廉等特点。因此,具有广泛的应用价值和市场开发前景。

关 键 词:亚硝酸根  试纸  显色剂

Abstract:This text introduced a new preparation method of a test paper for measuring the content of nitrite through the experiment. We fixed the material of the test paper and color-developing reagent by experiment, and analyze the affecting factors in the process of preparing color-developing reagent.The result of the experiment showed that the qualitative medium-speed filter paper can be used as the material of the nitrite-detecting paper: color developing reagent A containing 4-aminobenzene sulfonamide and N-1 naphthyl ethylenediamine hydrochloride, and mixtures of 1:1 naphthylamine solution and sulfanilic acid solution as color developing reagent. Practical experiment indicates that the nitrite test paper has a series of features: small-volume , easy-carrying , conveniently-measuring ,low-cost,etc.So it has an extensive applied value and market development prospect.
Keywords:nitrite  test paper  developer
