20、 15749:2009 (E) 5 1 Scope This European Standard specifies three different methods (Methods A, B and C) for the determination of sulfur present in fertilizers extracts in the form of sulfates. Method A specifies the gravimetric method. Method B specifies the method using inductively coupled plasma o
21、ptical spectrometry (ICP-OES). Method C specifies the method using ion chromatography (IC). 2 Normative references The following referenced documents are indispensable for the application of this document.
