Certification of the total contents (mass fractions) of Cd, Co, Cu, Pb, Mn, Hg and Ni and the aqua regia soluble contents (mass fractions) of Cd, Pb, Ni and Zn in a light sandy soil : CRM 142RFunded under: FP3-MAT
This report describes the preparation as well as the homogeneity and stability studies of a light sandy soil reference material intended to replace the exhausted BCR sandy soil CRM 142. It also summarises the analytical work for the certification of the total contents and the aqua regia soluble contents (mass fractions of dry mass (micro-g/g)) of some elements. The report contains all the results and a description of the methods used to certify the total contents of Cd (0.34), Co (12.1), Cu (69.7), Pb (40.2), Mn (970), Hg (0.067) and Ni (64.5) and the aqua regia soluble contents of Cd (0.25), Pb (25.7), Ni (61.1) and Zn (93.3). It also gives an indicative value for the total Cr and Zn content and the aqua regia soluble contents of Cr, Co, Cu and Mn.
