Certification of the total contents (mass fractions) of Cd, Co, Cu, Pb, Mn, Hg, Ni and Zn and the aqua regia soluble contents (mass fractions) of Cr, Cu, Pb, Ni and Zn in a sewage sludge : CRM 145 RFunded under: FP3-MAT
This report describes the preparation as well as the homogeneity and stability studies of a sewage sludge reference material intended to replace the exhausted BCR sewage sludge CRM 145. 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 (3.50), Co (5.61), Cu (696), Pb (286), Mn (156), Hg (2.01), Ni (247) and Zn (2122) and the aqua regia soluble contents of Cr (307), Cu (707), Pb (282), Ni (251) and Zn (2137). It also gives an indicative value for the total Cr content and the aqua regia soluble contents of Cd, Co, Mn and Hg.
