[Effect of Free Ammonia on Ammonia Escape During an Ammonia Oxidation Process].

Huan jing ke xue= Huanjing kexue, 2017
This study used short process nitrification sludge to investigate the effect of high free ammonia (FA) on ammonia escape during ammonia oxidation. A sequencing batch reactor (SBR) was used to study the ammonia escape process under different FA concentrations.

Plasma ammonia is the principal source of ammonia in sweat

European Journal of Applied Physiology and Occupational Physiology, 1992
Sweat contains ammonia. However, neither its source nor factors affecting its concentration in the sweat are known. The aim of this study was to examine the effect of plasma concentrations of ammonia and urea on the concentration of ammonia in the sweat. Four groups of male volunteers were examined: one control, two after ingestion of ammonium chloride,

Ammonia−Water Cation and Ammonia Dimer Cation

The Journal of Physical Chemistry A, 2009
We have investigated the structure, interaction energy, electronic properties, and IR spectra of the ammonia-water cation (NH(3)H(2)O)(+) using density functional theory (DFT) and high-level ab initio theory. The ammonia-water cation has three minimum-energy structures of (a) H(2)NH(+)...OH(2), (b) H(3)N(+)...OH(2), and (c) H(3)NH(+)...OH.

Ammonia Transport

EcoSal Plus, 2004
This review reviews the ammonium/methylammonium transport (Amt) proteins of Escherichia coli and Salmonella enterica serovar Typhimurium. The Amt proteins and their homologs, the methylammonium/ammonium permease proteins of Saccharomyces cerevisiae , constitute a ...
