摘 要: 本文对亚硝酸根离子特种粉剂型试剂进行了制备研究。以对氨基苯磺酸和α一萘胺为原料 ,在催化剂RA和填料的适当配比及加工条件下 ,合成了该特种试剂 ,其灵敏度达到0 .0 5mg/L 。 The preparation mettod of special powdered reagent about nitrite (NO - 2)was studied in this paper.The special reagent was synthesized under the condition of processing and the appropriate proportion between catalyst and wad,in which p-aminobenzenesulfonic acid and a-naphthylamine were used as raw materials.Its sensitivity reaches 0.05mg/L,and it was exactly fit for freshwater cultivation.
