Ethanol as a blending component for petrol - Determination of inorganic chloride and sulfate content - Ion chromatographic method; German version EN 15492:2007
This European Standard specifies an ion chromatographic (IC) method for the determination of inorganic
chloride and of sulfate content in ethanol. The precision of the method was established for chloride content
from 4 mg/I to 30 mg/I. However, the precision of the method for sulfate content was not established yet.
NOTE Preliminary measurements showed that sulfate content can be determined from (4 to 10) mg/kg.
