Application of dielectric barrier discharge and plasma-chemical reactor for water purification from NH₄OH
Water purification from ammonium hydroxide was carried out by using two methods of processing: treatment with ozone generated by a dielectric barrier discharge (DBD) as well as processing in plasma-chemical reactor equipped with a water electrode and a diaphragm, where the main oxidation factors wer...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Water purification from ammonium hydroxide was carried out by using two methods of processing: treatment with ozone generated by a dielectric barrier discharge (DBD) as well as processing in plasma-chemical reactor equipped with a water electrode and a diaphragm, where the main oxidation factors were OH hydroxyl radicals. The volume of the treated aqueous solution was 300 ml and the NH₄OH concentration was 0.025 ml in both cases. The phenolphthalein test was used for visual analysis of the content of an aqueous solution of ammonia in water. The ozone concentration was about 5.8 mg/l in water with ozone injection from an ozone generator and 0.7 mg/l in a plasma-chemical reactor, respectively. The analysis of OH and NO radicals in the water-air gap of the plasma-chemical reactor was carried out using a spectrometer operated in the range of 200…800 nm. |
