摘　　要：依据铵盐与甲醛反应生成等物质量酸的原理,建立了一种快速测定高浓度含氨废水中氨氮含量的甲醛法。试验结果表明,甲醛法所测结果与国家标准分析方法比较无显著性差异。该方法的加标回收率范围为96％～103％,具有快速、简便的优点,对合成氨工业废水和生活污水中氨氮的测定结果令人满意。In this paper, principles of releasing an equivalent quantity of acid were used by ammonium salts reacted with formaldehyde. The formaldehyde method of rapid determination of ammonia nitrogen in high concentration ammoniated wastewater was established. The results shows, no significant difference was found between the method and standard analytical method. The recovery were 96%-103%. It has the advantage of convenience and rapidity. The method can be used to determine ammonia nitrogen in ammonia industry and urban sewage.
