In this work, the reduction wave of chloroform was studied by diffe rential pulse polarography (DPP) and square wave ‎voltammetry (SWV). The effects of supporting electrolyte and solvent were discussed. In DPP experiments, the ‎reduction wave of chloroform was observable in aqueous solutions of tetramethylammonium bromide (TMABr) and tetra ‎ethylammonium bromide (TEABr) as the supporting electrolytes. Water, ethanol and dimethylsulfoxide (DMSO) were ‎examined as solvents to find the most suitable solvent. Square wave voltammetry technique was chosen to study the ‎quantitative parameters in different solvents. DMSO proved to be the best due to its sensitivity, reproducibility, limit ‎of detection and strong interaction with chloroform. Cyclic voltammetry was employed in order to elucidate the electrode ‎reaction mechanism. Bromoform was also studied and the differences between the electrode reaction mechanisms of ‎chloroform and bromoform were distinguished.‎
