Analysis of Chloride and Sulfate Ions in Fuel Ethanol

User Benefits

- Easily evaluate chloride and sulfate ions in fuel ethanol in accordance with ASTM D 7319-07. - Data with good linearity and reproducibility can be obtained. - Reduces analysis time and improves usability.

Introduction

Ethanol for fuel is an alternative fuel derived from plants and is an environmentally friendly renewable energy source. It is mixed with gasoline and used as a fuel for automobiles. However, when chloride and sulfate ions are present in fuel ethanol, they form residues in the engine and cause engine malfunction. ASTM D 4806-08a specifies standards for fuel ethanol, which specify that the concentration of chloride ion in fuel ethanol is 40 mg/kg or less and that ASTM D 7319-07 describes an analytical method for measuring chloride and sulfate ions in fuel ethanol using ion chromatography. of sulfate ion is 4 mg/kg or less. This article introduces chloride and sulfate ions analysis using the suppressor ion chromatograph HIC-ESP in accordance with ASTM D 7319-07.
