“…B108 (2004) 29-60 31 resulting most likely from poor management of temperature changes and control in the experimental procedures, as discussed by Dasgupta and Dong [8]. At the other extreme, Shi et al [9] report values that are much lower than other researchers.…”

“…Dasgupta and Dong [8] used dilute solution ammonia (0.002-0.1 M) in phosphate buffers (pH 6-10). The activity coefficient for the ammonium ion was calculated using the model of Laitinen and Harris [13] that accounts for the effect of the overall ionic strength of the solution and the activity coefficient for (NH3)aq was set as 1.…”

This paper discussed the effect of ammonia concentration adsorbed on fly ash for the ammonia emission as AAFA (Ammonia Adsorbed Fly Ash) produced from coal fired plants due to operation of NOx reduction technologies was landfilled with distilled or sea water at closed and open systems, respectively. Ammonia bisulfate and sulfates adsorbed on fly ash is highly water soluble. The pH of ammonium bisulfate and sulfate solution had significant effect on ammonia odor emission. The effect of temperature on ammonia odor emission from mixture was less than pH, the rate of ammonia emission increased with increased temperature when the pH conditions were kept at constant. Since AAFA increases the pH of solution substantially, NH 3 in the ash can release the ammonia order unless it is present at low concentration. NH 4 + ion is unstable in fly ash and water mixtures of high pH at open system, which is changed to nitrite or nitrate and then released as ammonia gas. The proper conditions for < 20 ppm of ammonia concentration released from the AAFAs landfilled in ash pond were explored using an open system with sea water. It was therefore proposed that optimal operation to collect AAFA of less than 168 ppm ammonia at the electrostatic precipitator were controlled to ammonia slip with less than 5 ppm at SCR/SNCR installations, and, ammonia odor released from mixture of fly ash of 168 ppm ammonia with sea water under open system has about 20 ppm.

“…Increasing the salinity of water can cause a "salting-out" effect, thus lowering ammonia solubility at a single temperature (Dasgupta and Dong, 1986;Lang et al, 1998). This effect is small in most natural fresh waters but can become significant in solutions of higher salinity such as seawater and brines (Bower and Bidwell, 1978).…”
