Inthis Standard, wet chemical methods are described.Thi

40、s Standard is intended for the determination of the minor elements Arsenic, Cadmium, Cobalt,Chromium, Copper, Mercury, Manganese, Molybdenum, Nickel, Lead, Antimony, Vanadium, and Zinc inall solid biofuels. Further, it describes methods for sample decomposition and suggests suitableinstrumental meth

41、ods for the determination of the elements of interest in the digests. Thedetermination of other elements such as Selenium,Tin, and Thallium is also possible with the methoddescribed in this Standard.This Standard was reviewed for Canadian adoption by the CSA Technical Committee on Solid Biofuels,und
