Effect of Anion and Cation on Ecotoxicity of Ionic Liquids towards Different Microbes

Ionic liquids (ILs) have been used in industrial application including electrochemical, chemical engineering, chemistry and others. ILs can be easily tuned by combining selected cation and anion in order to achieve desired characteristics. Nowadays, all industries are trying to use green application. However, the information regarding the toxicity of ionic liquids are still limited. The objective of this study is to evaluate the toxicity of ionic liquids towards selected microbes. The effect of anion and cation on the toxicity of ionic liquids also have been discussed. Toxicity of ionic liquids are determined by conducting Minimum Inhibitory Concentration (MIC) test. MIC test is conducted and the results obtain used to determine EC50 value for each microorganism towards different ionic liquids determine by plotting dose-response curve graph. The findings from this research are hydroxide anion and phosphonium cation found to be toxic towards microorganisms. While ammonium cation and acetate anion is found to be non –toxic towards microorganisms
