Abstract:
Alternative fuels, such as ethanol from plant sources, have gained popularity as a substitute for non-renewable petroleum fuels. Denatured ethanol can contain high concentrations of engine-damaging chloride and sulfate, making it important to determine their concentrations. Ion chromatography (IC) with suppressed conductivity detection is an accurate and sensitive method for these determinations, as described in ASTM method D7328. This poster demonstrates the determination of potential chloride and sulfate in E85 ethanol fuel (85% ethanol, 15% gasoline) following ASTM D7328 using an anion-exchange column with carbonate eluent and electrolytic suppression and facilitated on a compact IC system.
