Ethanol as a blending component for petrol - Determination of phosphorus, copper and sulfur content - Direct method by inductively coupled plasma optical emission spectrometry (ICP OES)

Asnjë informacion i shtuar.

This European Standard specifies an inductively coupled plasma optical emission spectrometry (ICP-OES) method for the direct determination of elements content in ethanol, namely phosphorus in the range (0,13 to 1,90) mg/kg, copper in the range (0,050 to 0,300) mg/kg, and sulfur in the range (2,0 to 15,0) mg/kg. WARNING - The use of this method may involve hazardous equipment, materials and operations. This method does not purport to address to all of the safety problems associated with its use, but it is the responsibility of the user to search and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. NOTE For the purposes of this document, the terms "% (m/m)" and "% (V/V)" are used to represent respectively the mass fraction (w) and volume fraction (greek symbol phi).
