摘要
建立流动分析法测定吸收液中氨的方法,用稀硫酸溶液吸收空气中的氨气,吸收液作为样品进入流动分析系统,采用在线蒸馏,实行自动分析,与国家标准方法比对,无明显差异,可用于空气中氨的定量检测。
By using the online distillation and implementing automatic analysis,a flow analytical method to determinate ammonia content in absorption liquid is established with ammonia absorption of atmosphere by dilute sulfuric acid solution and absorbent being as samples entering into the flow analysis system.Based on the comparison with the national standard method,the above method has no significant differences and can be used to quantitatively detect ammonia concentration in air.
