AN290: Determination of Total and Potential Sulfate and Total Chloride in Ethanol According to ASTM Method D 7319
Description
When combined with gasoline, ethanol increases octane levels and promotes better fuel burning. However, ethanol can be contaminated with chloride and sulfate, which can contribute to plugging and corrosion of automobile engines. This study describes a simple and direct injection IC method to determine total and potential sulfate and chloride in ethanol used as a gasoline additive. This method is consistent with ASTM method D 7319, which is intended for the analysis of ethanol samples containing 1.0–20.0 mg/L of total or potential sulfate and 1.0–50.0 mg/L of chloride.| Market: | Petrochem, Oil and Gas |
