Abstract:

BP-BF4 ionic liquid is prepared by the double decomposition reaction of BPC and NaBF4. The ionic liquid at room temperature used in the experiment has a significSubscript textant absorption determined by UV spectrum within the range of 200-400nm, the maximum absorption wavelength of BP-BF4 ionic liquid is 256nm. The standard working curve of BP-BF4 ionic liquid is Subscript texty=0.02852x+0.02406 (R=0.99933). The recovery rate of BP-BF4 ionic liquid which is between 99.6% and 102.2%, is measured by standard addition method in water. The quantitative analysis of BP-BF4 ionic liquids in water using ultraviolet spectroscopy is simple, accurate and reliable.
