The ammonium content was determined by the distillation method and total nitrogen content was determined using Devarda's alloy. The vapor pressure was measured by the technique described elsewhere [1].", "reference": {"citation": "Vrevskiy, M. S.; Zavaritskiy, N. N.; Sharlova, L. E. Zh. Russ. Fiz. -Khim.
