Insights into 1-butyl-3-methylimidazolium hydrogen sulfate recovery from wastewater by electrodialysis with heterogeneous ion-exchange membranes

Popis výsledku v původním jazyce

Due to the negative impact of ionic liquids (ILs) on the environment and their high cost, it is very important to examine their recovery and recycling methods. Thus, in this study, research on 1-butyl-3-methylimidazolium hydrogen sulfate ([Bmim]HSO&lt;inf&gt;4&lt;/inf&gt;) recovery from wastewater by electrodialysis (ED) is presented. The influence of the initial [Bmim]HSO&lt;inf&gt;4&lt;/inf&gt; concentration, the voltage, and the linear flow velocity on the effective [Bmim]HSO&lt;inf&gt;4&lt;/inf&gt; recovery was examined. To assess the effectiveness of the proposed method, factors such as IL percentage recovery, degree of concentration, electric current efficiency, and energy consumption were determined. It was found that as the initial concentration of [Bmim]HSO&lt;inf&gt;4&lt;/inf&gt; in the feed solution increased from 0.01 to 0.2 M, the [Bmim]HSO&lt;inf&gt;4&lt;/inf&gt; recovery efficiency increased. A 2.3-fold concentration of the [Bmim]HSO&lt;inf&gt;4&lt;/inf&gt; in the concentrate solution with a recovery of 98.8%, a current efficiency of 67.3%, and energy consumption of 28 kWh/m&lt;sup&gt;3&lt;/sup&gt; was achieved for ED of a 0.2 M [Bmim]HSO&lt;inf&gt;4&lt;/inf&gt; solution using heterogeneous ion-exchange membranes. Additionally, the voltage and linear flow velocity affected the [Bmim]HSO&lt;inf&gt;4&lt;/inf&gt; recovery. The highest ED efficiency for the recovery and concentration of [Bmim]HSO&lt;inf&gt;4&lt;/inf&gt; was obtained at an applied potential of 4 V, a 2 cm/s linear flow velocity, and 0.2 M IL in the feed solution.
