Effect of SO_2 on the Viscosity of Tetrabutylammonium Bromide Aqueous Solution

摘要

Tetrabutylammonium bromide (TBAB) aqueous solution could effectively absorb SO_2. To well know effect of sulfur dioxide on the properties of TBAB mixtures, the viscosity of the tetrabutylammonium bromide aqueous solution and the mixtures containing SO_2 and TBAB aqueous solution were measured. The results show that the viscosity of TBAB aqueous solution decreases with the increase of temperature and decrease of concentration. When the TBAB aqueous solution absorbs SO_2, the solution is divided into two layers, supernatant and lower course. The supernatant solution viscosity remains stable along with the temperature changing. However the lower course viscosity sharply increases with the temperature and concentration incremental.
