Determination of N-Heptyl Pyridine Tetrafluoroborate in Water Using UV–Spectrum

Abstract:

HEP-BF₄ ionic liquid is prepared by the double decomposition reaction of HEPB and NaBF₄. The ionic liquid at room temperature used in the experiment has a significant absorption determined by UV spectrum within the range of 200-400nm, the maximum absorption wavelength of HEP-BF₄ ionic liquid is 252nm. The standard working curve of HEP-BF₄ ionic liquid is y=0.01529+0.00972X (R=0.99926). The recovery rate of HEP-BF₄ ionic liquid which is between 95.8% and 101%, is measured by standard addition method in water. The quantitative analysis of HEP-BF₄ ionic liquids in water using ultraviolet spectroscopy is simple, accurate and reliable.
