摘      要：Volatile organic compounds(VOCs)are difficult to be eliminated safely and effectively because of their large concentration ***,maintaining a stable concentration of VOCs is a significant *** this research,H2O,Tween-80,[Emim]BF4,[Emim]PF6,and[Hnmp]HSO4 were applied to absorb and desorb simulated *** ionic liquid[Emim]BF4 demonstrated the best performance and was thus selected for further *** the ionic liquid acted as a buffer,the toluene concentration with a fluctuation of 2000–20000 mg·m-3 was stabilized at 6000–12000 mg·*** distillation(90°C)was highly efficient to recover[Emim]BF4 from *** regenerated[Emim]BF4 could retain its initial absorption capacity even after multiple ***,[Emim]BF4 had the same buffer function on various aromatic hydrocarbons.
