Abstract:

1-methyl-3-butyl Imidazole nitrate is prepared by BMIC and NaNO3 in the acetone. Scanning ionic liquid in 200~400nm wavelength range, get UV-spectrum curve. The ionic liquid used in the experiment has obvious absorption in 200~400nm wavelength range, and the maximum absorption wavelength determined by ultraviolet spectrometry method is 224nm. Linear regression equation is y=0.02559x-0.00942. Correlation coefficient is 0.99976, indicating there is high related degree between the solution concentration and the absorbance value. The linear range of BMINO3 ionic liquid in the water is 1-75 mg/L. Take samples randomly and have a repeated determination 5 times, the precision is RSD=0.25%, the recovery rate is between 97.4%~102%.
