We use conventional, microwave and ultrasound assisted sequential extraction, of defined
time and power, techniques for extractions of Cd, Cu, Cr, Ni, Pb and Zn in sediments and …

In this paper, the main objective was fractionation of Cd, Cu, Ni, Pb, Zn, Ca, Fe, and K in
certificate material and sediment samples gathered from and around the Petrochemical …

The current BCR procedure for metal fractionation recommended by the Standard
Measurement and Testing Programme requires rather time-consuming sample pretreatment …

In this paper we investigate alternatives to mechanical stirring for the extraction of the mobile
fraction of metals from sediment, and analyze whether these techniques can reduce …

This study deals with the problems of intensification of sequential extraction scheme,
proposed by the European Community Bureau of Reference (BCR). The conventional …

Purpose The purpose of this research was to assess the precision and accuracy of a BCR
and Tessier microwave-assisted sequential extraction procedure, in comparison to the …

In a research of chromium availability, the three-stage sequential extraction procedure,
proposed by European Community Bureau of Reference (BCR), has been applied for the …

BCR methods are known for leaching of heavy metals in sediment material. However, there
is no optimization of modification BCR using a microwave in Fe in the Gulf of Prigi sediment …

Sequential extraction procedure proposed by the European Standards, Measurements and
Testing (SM&T) Program, formerly the Community Bureau of Reference (BCR), has been …

Two alternative extraction methods—a routine ultrasonic bath and a microwave oven—were
