Abstract:
In the present paper, the authors used FTIR spectra measurement to analyze the volatilization of NH3 of different fertilizers. With the help of HITRAN database, using NLLS arithmetic, the authors retrieved the concentrations of NH3. The authors compared the concentrations and simply analyzed the reason why the concentrations are different. This experiment indicated that the FTIR spectra measurement used to analyze the volatilization of NH3 has many advantages, such as simple operation, high efficiency, measuring in real time and continuity, so this measurement can completely satisfy the demand of analysis in field.
