Using gas chromatography testing, the early stages of our experimentation yielded resins
XAD4 and L-493 as the most effective for removal of 1,4-dioxane per mass of resin. Based on
background research, the two resins were a viable option for adsorption because both have
properties that enabled them to adsorb oil and gas compounds in solution. Since both of these
resins showed promise through early experimentation, they were further tested at various
concentrations to try to create an isotherm as well as reproducible data and methods for 1-4-
dioxane removal.
