用纳氏试剂分光光度法,已算出氨氮曲线的公式,如何将吸光度代入公式算氨氮的浓度,

纳氏试剂分光光度法测水中氨氮对显色的时间和显色浓度有很大的要求,显色时间应在25°左右控制在15-30min,少于这个时间显色不充分,多于这个时间显色值偏大,显色浓度偏大时加入掩蔽剂时容易出现浑浊,不知道是不是这方面的问题

标准系列很纯没杂质,而样品含量是少数的分光比色之前发现有沉淀时需要过滤的,沉淀会影响吸光度的 还有要控制溶液的酸度很关键

译文如下：
Abstract: the water ammonia nitrogen content is water contaminated with the degree of the major indexes self-purification nano's reagent spectrophotometry, ammonia nitrogen in water method is simple, rapid, high sensitivity, is testing the water content of ammonia nitrogen is the most commonly used method. This paper adopts Leonard's reagent spectrophotometry relatively accurate measurements of fuyang normal college ammonia in west qinghe water nitrogen content, testing results show that the content of ammonia nitrogen in water 0.513 muon g/mL, content is on the high side. As the campus living areas crowded, contains a lot of ammonia nitrogen organic life water discharge into water, the microbial decompose role in, make ammonia nitrogen content increase greatly.
