摘要

Laboratory studies and theoretical calculations were performed to study the equilibrium chemistry of ammonia in aqueous solutions representing those found in natural waters and in the soil solution. The objectives of the study to determine the selectivity coefficient for calcium-ammonium exchange on a soil separate under controlled laboratory conditions. The Vaneslow convention was used to describe the exchange reaction between soluble ammonium and calcium on an exchange phase isolated from a Chalmers silt loam soil. Use of nitrate salts for calcium and ammonium minimized any soluble complex formation during exchange studies. A series of theoretical calculations were also conducted to evaluate the potential for ammonia loss from aqueous solutions treated with different ammoniacal compounds and also containing calcium carbonate or an exchange phase.
