| Abstract: | 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. |
