16、64:2018 (E)IntroductionThe preparation of this document was based on a mandate given to CEN by the European Commission and the European Free Trade Association (Mandate M/335) concerning the modernization of methods of analysis of fertilizers in the framework of Regulation (EC) No 2003/2003 1.Aqua re
17、gia is applied for determination of many elements in different matrices. A horizontal standard for aqua regia extraction of soils, sludges and biowaste was prepared by CEN/TC 400. Similar procedure was applied for determination of the aqua regia extractable content of arsenic, mercury, cadmium, chro
18、mium, nickel and lead in fertilizers and liming materials (European Standard prepared by CEN/TC 260). Wide use of the aqua regia extraction and possibility to prepare a suitable horizontal standard was the main reason to develop the given extraction procedure.WARNING Persons using this European Stan
19、dard should be familiar with normal laboratory practice. This European Standard does not purport to address all of the safety issues, if any, associated with its use. It is the responsibility of the user to establish appropriate health and safety practices and to ensure compliance with any national
20、regulatory conditions.IMPORTANT It is absolutely essential that tests conducted according to this European Standard are carried out by suitably trained staff.4BS EN 16964:2018EN 16964:2018 (E)1 ScopeThis European Standard specifies a method for the total extraction of boron, cobalt, copper, iron, ma
21、nganese, molybdenum and zinc with aqua regia from mineral fertilizers containing one or more micro-nutrients.The extracts can be analysed according to EN 16963, EN 16965, prEN 17041, prEN 17042 and prEN 17043.This method is also suitable for the extraction of cadmium, chromium, nickel and lead to be
22、 determined according to EN 16319; the extraction of mercury to be determined according to EN 16320 and the extraction of arsenic to be determined according to EN 16317.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensab
