Abstract:

1-methyl-3-butyl Imidazole tetrafluoroborate is prepared by BMIC and NaBF4 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 221nm. Linear regression equation is y=0.01128x+0.027. Correlation coefficient is 0.99957, indicating there is high related degree between the solution concentration and the absorbance value. The linear range of BMIBF4 ionic liquid in the water is 1-75 mg/L. Take samples randomly and have a repeated determination 5 times, the precision is RSD=0.29%, the recovery rate is between 99.0%~102.3%.
