초록/요약
Nitrogen is a very common element both in the atmosphere and in the water. The effect on temperature to the nitrogen compounds has been observed by constructing the nitrogen-water Pourbaix Diagram at 278 K, 288 K, 298 K, 308 K, and 318 K. Typically, between pH -2 to 16, nitrogen was examined to be stable as NO3-, NH4+, NO2-, and NH4OH. The absolute values of the slope of the boundary line between each chemical species were shown to increase as the temperature increases. The area of each chemical species in a stable state was calculated to compare the tendency of existing form of each chemical species. The areas of the stable region for NH4+ was observed to decrease with temperature, while those for NO3-, NH4OH, and NO2- were investigated to increase linearly as the temperature increases. The thermodynamical calculation applied in this study is expected to be further studied and applied to water control and purification of water from contamination such as algal bloom.
