| 摘 要： | 为了监控制革废水中亚硝酸盐和氨氮的含量,建立了一种简单、精确、灵敏的反向参比流动注射分光光度法(rrFIA),用于测定制革废水中的亚硝酸盐和氨氮。该法基于亚硝酸盐(NO2-)与磺胺-N(1-萘基)-乙二胺(END)偶合生成紫色染料,在525nm波长处有吸收,从而可用此法定量检测样品中NO2-浓度。其过程是氨氮先被氧化液完全氧化为NO2-,检测出的新生成的NO2-的含量,即为氨氮的含量。试验过程中进行了测定条件的优化。在最佳试验条件下,该方法在2·0~500·0μg/L的范围内,NO2-浓度与峰高成良好线性关系,检出限为0·7μg/L相对标准偏差为0·844%。试验表明:这种方法适合在线自动分析制革废水中的亚硝酸盐和氨氮的含量。

| Abstract: | In order to control the pollution of nitrite (NO2-) and ammonium in tannery effluent, a simple, accurate and sensitive reverse reference flow injection analysis (rrFIA) spectrophotometric method was developed and presented. The method was based on the principle of coupling reaction between NO2- and sulfanilamide-N-1-naphthyl ethylenediamine hydrochloride (END). Ammonia was firstly oxidized into NO2-, and then the content of new NO2- was the content of ammonium in samples. The absorbance of the complex was m... |
