Herein we report the synthesis of new hydrophobic ionic liquid by simple manipulations starting from d-galactose. The synthesized ionic liquid 1-methyl-3-(((3aS,5S,5aR,8aR,8bS)-2,2,7,7-tetramethyltetrahydro-3aH-bis([1,3]dioxolo)[4,5-b:4′,5′-d]pyran-5-yl)methyl)-1H-imidazol-3-ium hexafluorophosphate(V) (IL 5) was completely characterized by sophisticated analytical techniques. IL 5 was investigated as adsorbent for the sequestration of Pb2 + ions from aqueous solution and this is proved as its potential application. Batch mode studies were done, by varying the batch parameters such as pH, IL dose, contact time, initial metal ion concentration and temperature. Various mathematical models such as kinetic models and isotherms were employed to understand the mechanism of sequestration. Thermodynamic investigations suggest that the sequestration of Pb2 + ions is spontaneous and exothermic in nature. The maximum loading capacity of IL 5 was found to be 374.9 mg g− 1. Desorption and regeneration analysis revealed the repeated use of IL 5 in industrial processes. These results suggest that IL 5 is a potential sorbent for the elimination of Pb2 + ions from aqueous solution.
