Solid Biofuels - Determination of minor elements

This Technical Specification is intended for determination of the minor elements Arsenic, Cadmium, Cobalt, Chromium, Copper, Mercury, Manganese, Molybdenum, Nickel, Lead, Antimony, Vanadium and Zinc in all solid biofuels. Further it describes methods for sample decomposition and suggests suitable instrumental methods for the determination of the elements of interest in the digests. The determination of Selenium, Tin and Thallium is also possible with the method described in this Technical Specification.

This Technical Specification (CEN/TS) was approved by CEN on 22 November 2005 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania,
Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

Introduction
The minor elements present in solid biofuels can in some cases be of environmental concern, e.g. it has been
shown that certain energy crops will concentrate cadmium and in polluted areas other toxic elements may be
found at elevated concentrations in the biofuels. This can be a problem if for example the ash from the
combustion is to be put back in the forest as a fertilizer. Trace elements in biofuels are often present at very
low concentrations requiring great care to avoid contamination in the sample preparation and decomposition
steps. The typical concentrations of minor elements in solid biofuels can be found in CEN/TS 14961. In this
technical specification wet chemical methods are described. Alternative methods such as X-ray fluorescence
(XRF) or direct mercury analysers may be used when validated with suitable materials (biomass reference
materials)
