Abstract
Tetrahydrofuran-water mixture is a satisfactory medium for polarographic studies of certain organic compounds. It is particularly adaptable for routine analyses becaues it may be purchased in a relatively pure form and any small amounts of impurities present may be quickly and easily removed by passing it through a column of activated alumina. Tetrahydrofuran has good solvent action for supporting electrolytes such as tetrabutylammonium iodide and for many organic compounds. The diffusion currents obtained for organic compounds in this medium are higher than those obtained in dioxane-water solvent. Biphenyl and the terphenyls can be determined quantitatively using this medium and reduction waves also were obtained for p-bromo-diphenyl, nitrobenzene, naphthalene, triphenylene, 2-bromonaphthalene, anthr acene, and pyrene.
