摘要

In this paper, five reference materials for arsenic speciation have been developed,which were collected from Shanxi Province and Nei Monggol,typical areas with a high background of arsenic.The analytical results indicate that the reference materials were homogeneous and stable.A multi-laboratory collaborative analysis scheme was adopted in the certification procedure.The determination methods were accurate and reliable with reasonable certified values and uncertainties.Moreover,lyopyilization,which is commonly used in the medical profession in order to guarantee the sample stability,was primarily applied to the preparation of the standard reference materials.This series of reference materials fills the gaps at national and international levels.
