| Summary: | Ionic liquids have become increasingly common and favourable as a new alternative for traditional solvents. However, the low biodegradability of ionic liquids is causing hesitations as its usage proves to potentially lead to additional of persistent pollutants in water bodies and ultimately result in negative impacts to the environment. Several existing methods to degrade ionic liquids can lead to the formation of secondary pollutants which require further treatment. In this study, the degradation of 1-butyl-3-methylimidazolium chloride (BMIMCl) in microbial fuel cell was investigated. It was found that more than 96% of 1 ppm of BMIMCl can get fully degraded in a microbial fuel cell within 72 hours. Addition of BMIMCl can also increase the oxidation rate of other organics present, which resulted in more power being generated. Investigations were carried out using GC and LC/MS system. Electrochemical tests were carried out on the microbial fuel cell, reflecting the power density was obviously increased with the presence of BMIMCl. More studies needed to be done in the future. |
