摘要
根据铵盐与甲醛反应生成等物质量酸的原理,建立了用甲醛法测定ADC发泡剂废水中氨氮含量的分析方法。结果表明,甲醛法所测结果与纳氏试剂国家标准分析方法比较无显著性差异,加标回收率范围为98%-103%。本法操作简便、快捷、经济、结果准确,便于实际应用。
In this paper,principles of releasing an equivalent quantity of acid were used by ammonium reacted with formaldehyde.The formaldehyde analysis method of rapid determination of ammonia nitrogen in ADC foaming agent wastewater was established.The results showed that no significant difference was found between the method and standard analytical method of Nessler＇s colorimetry.The recoveries are in the range of 98%～103%.This method is simple,rapid,economical,accurate and easy to practical application.
